Google's Play Integrity API bans using GrapheneOS despite it being far more secure than anything they permit. It also bans using any other alternative. This isn't somehow specific to an AOSP-based OS. You can't avoid this by using a mobile OS based on FreeBSD instead. You'll just be more locked out.

Google's Play Integrity API permits devices with no security patches for 10 years. The device integrity level can be bypassed via spoofing but they can detect it quite well and block it once it starts being done at scale. The strong integrity level requires leaked keys from TEEs/SEs to bypass it.
Play Integrity API is highly insecure and it isn't particularly hard to temporarily bypass it. There are frameworks for spoofing the software checks and leaked keys for bypassing hardware attestation can be purchased. However, bypasses are getting harder and are becoming increasingly short lived.
It doesn't provide a useful security feature, but it does lock out competition very well. Services requiring Apple App Attest or Google Play Integrity are primarily helping to lock in Apple and Google having a duopoly for mobile devices. Play Integrity is more relevant due to AOSP being open source.
Governments are increasingly mandating using Apple's App Attest and Google's Play Integrity for not only their own services but also commercial services. The EU is leading the charge of making these requirements for digital payments, ID, age verification, etc. Many EU government apps require them.
Instead of governments stopping Apple and Google from engaging in egregiously anti-competitive behavior, they're directly participating in locking out competition via their own services. Requiring people to have an Apple device or Google-certified Android device is anti-competition, not security.
@GrapheneOS do not know almost anyone else who is making this exact point that "security" is a euphemism for "national security" and is actively opposed to privacy or auditability. certainly not user security. @dwaynemonroe has identified the extreme closeness of monopolistic and fascistic hierarchical unaccountable and potentially even illegal control
