This is pretty incredible. These aren't just good practices, they're the fairly bleeding edge best practices.

1. No more SMS and TOTP. FIDO2 tokens only.

2. No more unencrypted network traffic - including DNS, which is such a recent development and they're mandating it. Incredible.

3. Context aware authorization. So not just "can this user access this?" but attestation about device state! That's extremely cutting edge - almost no one does that today.

My hope is that this makes things more accessible. We do all of this today at my company, except where we can't - for example, a lot of our vendors don't offer FIDO2 2FA or webauthn, so we're stuck with TOTP.

I think 3. is very harmful for actual, real-world use of Free Software. If only specific builds of software that are on a vendor-sanctioned allowlist, governed by the signature of a "trusted" party to grant them entry to said list, can meaningfully access networked services, all those who compile their own artifacts (even from completely identical source code) will be excluded from accessing that remote side/service.

Banks and media corporations are doing it today by requiring a vendor-sanctioned Android build/firmware image, attested and allowlisted by Google's SafetyNet (https://developers.google.com/android/reference/com/google/a...), and it will only get worse from here.

Remote attestation really is killing practical software freedom.

I wish I had responded earlier, because now this entire thread is full of nonsense and I can't really respond to everything.

But attestation can mean a lot of things and isn't inherently in conflict with free software. For example, at my company we validate that laptops follow our corporate policy, which includes a default-deny app installation policy. Free software would only, in theory, need a digital signature so that we could add that to our allowlist.

Presumably (hopefully) these are corporate-owned devices, with a policy like that. Remote attestation is fine if it's controlled by the device's owner, and you can certainly run free software on such a device, if that particular build of the software has been "blessed" by the corporation. However, the user doesn't get the freedoms which are supposed to come with free software; in particular, they can't build and run a modified version without first obtaining someone else's approval. At the very least it suggests a certain lack of respect for your employees to lock down the tools they are required to use for their job to this extent.
