Android shouldn't be considered Open Source anymore, since source code is published in batches and only part of the system is open, with more and more apps going behind the Google ecosystem itself.
Maybe it's time for a third large phone OS, whether it comes from China getting fed up with the US and Google's shenanigans (Huawei has HarmonyOS but it's not open) or some "GNU/Linux" touch version that has a serious ecosystem. Especially when more and more apps and services are "mobile-first" or "mobile-only" like banking.
Allowing apps to say "we only run on Google's officially certified unmodified Android devices" and tightly restricting which devices are certified is the part that makes changes like this deeply problematic. Without that, non-Google Android versions are on a fair playing field; if you don't like their rules, you can install Graphene or other alternatives with no downside. With Play Integrity & attestation though you're always living with the risk of being cut off from some essential app (like your bank) that suddenly becomes "Google-Android-Only".
If Play Integrity went away, I'd be much more OK with Google adding restrictions like this - opt in if you like, use alternatives if you don't, and let's see what the market actually wants.
It’s funny to see the volume of comments on HN from folks who are outraged at how AI companies ferociously scrape websites, and the comments disliking device attestation, and few comments recognizing those are two sides of the same coin.
Play integrity (and Apple’s PAT) are what allow mobile users to have less headaches than desktops. Not saying it’s a morally good thing (tech is rarely moral one way or the rather) just that it’s a capability with both upsides and downsides for both typical and power users.
Play Integrity's highest level of attestation features requires devices to be running a security update which is within a sliding window of 1 year.
LOTS of Android devices have not released a security update in many many years. This forces users to unnecessarily upgrade to higher end OEMs.
Google is effectively pushing out Xiaomi, Huawei, and many others that offer excellent budget options. Google is not just offering you the comfort of not having to fill out CAPTCHAs on your phone, most importantly they are playing monopoly.
