It's an interesting article (and thanks to the author for putting it out) but I wonder what their end goal is. Is it to have a 100% secure/private phone? I'm not sure if that's possible with the proprietary firmware (though the hardware kill switches are certainly a good idea). Most importantly, the questionable usability means that either the Librem team needs to work much more, or... this becomes a "smarter" alternative to a dumb brick without giving data to Big Tech. (Ignoring the fact that a sim card automatically makes you lose privacy to the government/telecos).

When comparing against something like a Pixel running GrapheneOS, it's honestly a bit more puzzling to me. Granted, I'm definitely not the audience for this, but with G_OS you can do most things that a regular phone can do, without taking several minutes to install Firefox.

As much as I love privacy (going as far as having a semi-random username), this phone is a bit puzzling. I hope someone can throw more light on this.

The general idea behind any 'pure' Linux phone is to have a device that you can trust at least as much as a desktop running Linux. Security is definitely a key aspect for many. But it's also the flexibility of not being locked in to anything on the software side. Ideally, it also extends the useful life of the device as when vulnerabilities and bugs are found, they can be fixed rather than junking the device for lack of updates. It's still pretty early days re: 'full' Linux on mobile and so it doesn't look like much yet... it takes time. Desktop Linux didn't look like much in 1994 either.

I'm not familiar with GrapheneOS but I assume it follows the usual model when repurposing Android devices of taking various closed source blobs (i.e. drivers etc) and rebuilding the open source bits around them? If so, this approach usually locks you into a Linux kernel version to remain compatible with the blobs which limits you on kernel features and fixes as well as who knows what exposure the blobs have to offer, which also will likely never get updates.

GrapheneOS and AOSP are Linux-based and there are no closed source kernel modules. They aren't somehow not actual Linux due to not using systemd, glibc, binutils, GCC, pulseaudio/pipewire, polkit, NetworkManager, GNOME, etc. If that's what you mean, you should say so, because those userspace components are not Linux and not using those doesn't make it any less of a Linux distribution. Is Alpine not a real Linux distribution? Is it only a real Linux distribution if it looks like what you're familiar with? More developers are familiar with Android than the desktop Linux software stack. More work goes into it. Far more apps are written for it, and that includes a very active open source app ecosystem.

Sticking to an LTS kernel branch for the lifetime of the device isn't due to anything closed source. GrapheneOS only supports devices with proper security support for all the firmware, drivers, etc. and again there are no closed source kernel drivers. We can support pretty much any mobile device with alternate OS support since any serious one will have AOSP support. Most devices have lackluster security and don't meet our requirements. We're working with a hardware vendor to get a non-Pixel phone actually meeting reasonable security requirements.

Librem 5 has a bunch of components where they are not shipping updates. You have things very much backwards on that front. The Librem 5 does not come close to meeting the security requirements to run GrapheneOS. It has a bunch of poorly secured and insecurely configured legacy hardware often without proper updates available, components that are not properly isolated via IOMMU, no secure element or all the stuff that comes along with that (HSM keystore with a nice API used by apps, Weaver to make disk encryption work for users without a high entropy passphrase like 7 diceware words, insider attack resistance, working attestation not depending on hard-wiring hashes and a lot more) and many other things. The OS they use has a near total lack of any systemic overall privacy/security work or privacy/security model and only falls further and further behind. The most exciting feature for securing devices right now is hardware memory tagging support in ARMv9, but there are years and years of tons of important privacy/security work done in a systemic way across hardware/firmware/software which are missing there before worrying about stuff like that.

Marketing something as private/secure and spreading tons of misinformation and outright lies about the mainstream options doesn't make it secure or more secure than those. It's actually pretty funny that they mislead people about the isolation of hardware components like the cellular baseband in other devices when the vast majority of mainstream phones (iPhone, Pixel, Qualcomm SoC devices, Exynos SoC devices) have it done quite well when they don't. Strange that they get away with these games of misrepresenting things, hiding the fact that they still have entirely proprietary hardware and near entirely proprietary firmware for the SoC and other hardware components, etc. Hiding proprietary stuff doesn't make it go away. Not updating it doesn't make it go away and simply ensures a highly insecure device.

> More developers are familiar with Android than the desktop Linux software stack. More work goes into it. Far more apps are written for it, and that includes a very active open source app ecosystem.

The problem is that the Android app ecosystem has a very large number of apps which are based on collecting users' personal information and violating people's privacy, and it is hard for a normal user to avoid all the spyware and malware in Android. In my experience using CyanogenMod/LineageOS and the F-Droid repo since 2015, I inevitably fall back to installing some proprietary apps when using AOSP-derivatives, whereas my PinePhone and Librem 5 USA only have FOSS apps and drivers installed on them. If the goal is to use FOSS as much as possible, you are better off buying a Linux phone in my opinion.

By the way, one of the apps that I helped develop is on F-Droid (https://f-droid.org/en/packages/com.ketanolab.nusimi/ ) and I have given workshops on how to install LineageOS on phones, so I speak as someone who tries to promote the use of FOSS on Android phones, but the phone industry does put up a lot of barriers to make it difficult to install AOSP-derivatives.

> GrapheneOS only supports devices with proper security support for all the firmware, drivers, etc. and again there are no closed source kernel drivers. We can support pretty much any mobile device with alternate OS support since any serious one will have AOSP support. Most devices have lackluster security and don't meet our requirements.

The problem is that Google only sells Pixels in a very limited number of countries. Whereas Purism offers free worldwide shipping for the Librem 5, the Pixel 6 is only being sold in 8 countries (Australia, Canada, France, Germany, Japan, Taiwan, UK, USA), so your security requirements exclude over 90% of the world's population from being able to use GrapheneOS. Plus, many people don't want to financially support a company like Google which is based on Surveillance Capitalism.

> We're working with a hardware vendor to get a non-Pixel phone actually meeting reasonable security requirements.

Good to hear. I look forward to seeing it.

> Librem 5 has a bunch of components where they are not shipping updates.

Not true. Purism has promised to provide updates to the proprietary firmware on the Librem 5, and already provides instructions for how to update the firmware on the WiFi/BT and USB controller. See: https://source.puri.sm/Librem5/community-wiki/-/wikis/Freque...

> It has a bunch of poorly secured and insecurely configured legacy hardware often without proper updates available

What are you talking about? Purism purposely designed the Librem 5 to avoid planned obsolescence, so it looked for component suppliers who support their hardware for a long time. For example, NXP guarantees that that it will provide updates for the i.MX 8M Quad for 15 years (Jan. 2018 - Jan. 2033). See: https://source.puri.sm/Librem5/community-wiki/-/wikis/Freque...

In contrast, Google only promises to provide 3 years of OS updates and security updates for the Pixel 3/4/5, and 3 years of OS updates and 5 years of security updates for the Pixel 6. Qualcomm announced in Dec. 2020 that it will support its Snapdragon processors (which are used in Pixel devices) for 3 years of Android updates and 4 years of security updates.

Linux phones like the Librem 5 and PinePhone use separate components which are supported for many years by the manufacturers, whereas most Android phones (like the Pixels) use integrated mobile system-on-chips which are only manufactured for 1-2 years and only supported for 3-4 years by the manufacturer. Because Linux phones use components with long-term support by the component suppliers, the Librem 5 is the first phone to be sold with the guarantee of lifetime software updates, and PINE64 promised to manufacture the PinePhone for 5 years, which is longer than any other smartphone ever sold.

> components that are not properly isolated via IOMMU,

The Librem 5 doesn't need an IOMMU, because it uses separated components, and it uses serial buses (USB 2.0/3.0, SDIO, I2C and I2S) that don't allow direct memory access, so there is absolute no chance of the WiFi/BT, cellular modem, GNSS and USB controller being able to access the RAM or the SoC's cache. Unlike the Snapdragon processors in Pixels whose hardware is essentially a black box, we can independently verify by looking at the open source schematics that direct memory access is not possible in the Librem 5.

> but there are years and years of tons of important privacy/security work done in a systemic way across hardware/firmware/software which are missing there before worrying about stuff like that.

If you are talking about kernel hardening and running each app in its own sandbox with its own UID, then I would agree that Android/AOSP has more security features than Debian/PureOS, but the problem with your argument is that you are ignoring the fact that a mountain of spyware and malware has been created for the Android platform and users have to be very vigilant to not install any of it. According to AV-TEST, 3.38M pieces of malware and 3.18M potentially unwanted apps (mostly spyware) were created for the Android platform in 2021, whereas it is unlikely that any of that garbage will get into the Debian->PureOS repos to ever effect users of the Librem 5. Linux users rarely install anything from outside their distro's repo, whereas I often find myself installing apps whose code I can't verify when I use AOSP-derivatives because I can't find all the apps that I need in F-Droid.

Yes, Android/AOSP does have a lot more security built into its design than Debian->PureOS, but it is based on a model of letting all sorts of unverifiable and dangerous code run inside it. For more on the Librem 5's security, see: https://source.puri.sm/Librem5/community-wiki/-/wikis/Freque...

> Marketing something as private/secure and spreading tons of misinformation and outright lies about the mainstream options

Care to provide any evidence to prove that Purism or its employees are "spreading tons of misinformation and outright lies about the mainstream options"?

Since you're doing that yourself, I don't think engaging with you on the topic is productive. I responded here due to the inaccurate attacks on GrapheneOS from people promoting Purism products. Doubling down on spreading their inaccurate marketing / talking points isn't going to deter us from responding and we're more than happy to post a more detailed response on our site and across platforms. I already gave detailed responses and don't intend to repeat much of what I've already said.

> The problem is that the Android app ecosystem has a very large number of apps which are based on collecting users' personal information and violating people's privacy, and it is hard for a normal user to avoid all the spyware and malware in Android.

If the goal is to use FOSS as much as possible, you are better off buying a Linux phone in my opinion.

There's a far larger and better ecosystem of open source apps for Android than there is for the products that you're marketing, and they can be used on secure devices rather than blatantly insecure ones not even meeting basic standards as I've already detailed in my responses.

> The problem is that Google only sells Pixels in a very limited number of countries. Whereas Purism offers free worldwide shipping for the Librem 5, the Pixel 6 is only being sold in 8 countries (Australia, Canada, France, Germany, Japan, Taiwan, UK, USA), so your security requirements exclude over 90% of the world's population from being able to use GrapheneOS. Plus, many people don't want to financially support a company like Google which is based on Surveillance Capitalism.

Pixels can be purchased internationally. They don't need to be bought from Google. Purism is a company based around spreading misinformation and marketing their products dishonestly which I know people in our community don't want to support. We're not going to support thoroughly insecure devices from a company which is unwilling to even admit to the limitations/weaknesses let alone fixing them and producing something we could ever consider supporting. The experience we had with them is that they only want to use the name of projects like ours to promote themselves as partners without doing anything on their part. They engaged in libel/harassment/bullying targeting our developers in response to us not supporting their phone as a target and explaining why within our community. I see what you're doing here as an extension of their dishonest marketing and inaccurate attacks on other platforms/projects/products. If this is going to be something that's happening regularly, we'll add detailed documentation / articles to our site about the topic to reference so we don't need to keep writing up the same things.

> Not true. Purism has promised to provide updates to the proprietary firmware on the Librem 5, and already provides instructions for how to update the firmware on the WiFi/BT and USB controller.

There aren't full firmware security updates for the Librem 5 and what I said is completely accurate. What's even worse is that they do not ship the incomplete updates that could be available and they did things in a way that makes it impossible to even ship all of those as part of an OS. Please don't claim that my completely accurate description of the situation is not true based on something that's not in any way debunking what I said.

> What are you talking about? Purism purposely designed the Librem 5 to avoid planned obsolescence, so it looked for component suppliers who support their hardware for a long time. For example, NXP guarantees that that it will provide updates for the i.MX 8M Quad for 15 years (Jan. 2018 - Jan. 2033).

They're unable to provide full security updates from day one and the device is already end-of-life in terms of what that means for GrapheneOS. It would have to be marked as end-of-life from day one if we added support for it. We would be unable to declare any Android security patch level for the device due to it not meeting the basic security requirements and not having full firmware security updates available. What I've said is true, and you're just claiming otherwise based on their deliberately very incomplete and misleading marketing.

> In contrast, Google only promises to provide 3 years of OS updates and security updates for the Pixel 3/4/5, and 3 years of OS updates and 5 years of security updates for the Pixel 6. Qualcomm announced in Dec. 2020 that it will support its Snapdragon processors (which are used in Pixel devices) for 3 years of Android updates and 4 years of security updates.

Those are minimum guarantees of full security updates, not end-of-life dates and the number of days you get those for the Librem 5 is ZERO. The only recommended devices for GrapheneOS are the Pixel 6 and Pixel 6 Pro, which means that there is at least 5 years of full security updates for the devices we support. You can see from our site that we continue providing extended support releases which we mark as insecure past the end-of-life of devices. A device is end-of-life as soon as any important component no longer provides the proper monthly security updates. How can we support the Librem 5 even aside from all the missing security features which have already been explained elsewhere, when we would be unable to provide anything close to the March 2022 security update, and would be unable to ship all the updates that are available through the OS?

> Linux phones like the Librem 5 and PinePhone use separate components which are supported for many years by the manufacturers, whereas most Android phones (like the Pixels) use integrated mobile system-on-chips which are only manufactured for 1-2 years and only supported for 3-4 years by the manufacturer.

This is completely inaccurate. They still use an SoC and the components they've chosen do not provide a longer period of support in the sense that Android expects in order to declare the latest security patch level. Several of their component choices including the radios rule that out, as does the way they are integrated. Your claim of lifetime security updates is completely bogus and demonstrates the extreme lengths Purism goes to in order to mislead people and profit from it. They still need firmware support and all the drivers, etc. still need to be maintained. There's really no point of engaging with people lying through their teeth and pushing all their inaccurate talking points so I'm not going to keep engaging with you much further.

Linux doesn't mean systemd, polkit, glibc, GCC, binutils, GNOME, pulseaudio/pipewire, Wayland/X11, etc. It makes no sense to claim these are Linux phones when the vast majority of smartphones run Linux. It's marketing spin. If you want to call it a GNU/Linux phone, go ahead, but what you're doing is a deliberate attempt at misleading people on their part.

> The Librem 5 doesn't need an IOMMU, because it uses separated components, and it uses serial buses (USB 2.0/3.0, SDIO, I2C and I2S) that don't allow direct memory access, so there is absolute no chance of the WiFi/BT, cellular modem, GNSS and USB controller being able to access the RAM or the SoC's cache. Unlike the Snapdragon processors in Pixels whose hardware is essentially a black box, we can independently verify by looking at the open source schematics that direct memory access is not possible in the Librem 5.

This is not accurate. It still has an SoC with a ton of components aside from the SoC despite your inaccurate claim that it doesn't, and those components still need to be isolated with an IOMMU. The other components which you're talking about using USB are dramatically less isolated than the Qualcomm or Samsung baseband on mainstream devices. You're trying to present something dramatically worse as being better in this regard. Are you trying to claim that the Librem 5 doesn't have components like a GPU and other SoC components? The Librem 5 hardware is also just as much of a black box. It's 100% as proprietary. It does not have firmware or hardware that's any more open and this is a blatant lie. Them marketing the hardware as being more open is thoroughly unethically and dishonest. They've done the same with their laptops and other products, which has done immense harm to projects like Talos actually trying to produce open hardware in any actual sense of the word.

They've done the same with their laptops and other products, which has done immense harm to projects like Talos actually trying to produce open hardware in any actual sense of the word.

There is a major difference between the openness of the Librem 5 (L5) vs Android phones. The L5 is the first phone with free/open source schematics (GPL 3.0) for its circuit boards since the Golden Delicious GTA04A4 which was released in Jan 2012. Purism has only released the STL files for the L5's case and the board schematics in PDF, so it would take some work to recreate the original CAD files, but anybody can legally reproduce the hardware in the L5. To find a phone which released its CAD files, you have to go back to the OpenMoko Neo FreeRunner released in June 2008.

Purism has also released the board view images to show where components are placed on the L5's boards. You may be able to find the board view for a few models (such as iPhones), because they get leaked, but as far as I know, no Android phone manufacturer publicly releases the board views of their circuit boards.

If your argument is that the circuit boards don't matter, because most of the functionality is locked up in proprietary chips, then let's look at the chips that Purism selected and see if there's a difference. Qualcomm, MediaTek, UNISOC and Samsung don't release the documentation for their mobile application processors without an NDA, and Apple and Huawei don't release their documentation on their chips to any outside companies as far as I know. In contrast, NXP released 7000 pages of documentation plus their Android and Linux software for the i.MX 8M Quad to anyone who registers on their website. They restrict the security manual to only certain approved people, but everything else can be obtained and NXP has a public forum where anyone can ask questions about their i.MX processors. Likewise, Thales releases the documentation on the PLS8 cellular modem and provides a public forum.

Android phones commonly have a locked bootloader which prevents the user from changing the OS. All Huawei and Apple phones have the bootloader locked. Most Samsung phone require using an unauthorized crack. Motorola and Xiaomi require applying for an unlock code code and waiting up to two weeks for it and using it voids the hardware's warranty. Sony makes it easy but voids the warranty. Google also makes it easy, but won't honor the warranty unless the Pixel is reflashed to the original OS and relocked. In contrast, the Librem 5 has such restrictions.

Another issue is the drivers and kernels. Qualcomm has the best track record of the major mobile SoC manufacturers since it provides public access and the commit record to its kernel source code at Code Aurora, but the community has to take that code and adapt it to work in mainline Linux and it often takes 3 or 4 years to fully support Snapdragons. Samsung has done better in recent years, but MediaTek, UNISOC, Huawei and Apple are horrible. However, NXP is far better than all these since it commits directly to mainline Linux and is willing to work with the community to support its chips.

Purism develops its code in public and encourages its developers to interact with the community. All the firmware in the L5 is proprietary, but it is worth mentioning that Purism is planning on using FOSS firmware in its secondary Cortex processor to control the smartcard reader. Also the OpenPGP specification is open, so anyone can study it.

I would argue that all of these things add up to make the Librem 5 the most open phone that can be bought today (with the PinePhone a close second). I have a problem with some of Purism's marketing, like the "100% made in the USA electronics" slogan for the Librem 5 USA, but you have to look at this in the context of the actual mobile industry and what is possible in the real world. Sure it would be great to have a phone with open hardware chips, but you are talking about hundreds of millions of dollars to develop those chips and paying hundreds of millions more to license the necessary IP, which is totally unrealistic.
