Not at all. They are one and the same. Both of those things will literally destroy the computer freedom we enjoy today.

GrapheneOS can attest to the device's security. The question is whether the app developers will trust such an attestation. Will they put money, time and effort into evaluating and trusting GrapheneOS? Of course not. They will just decide to trust nobody except Google and Apple.

This is the future. We'll be discriminated against. Can't even log into an account from an "unauthorized device". Their servers will just refuse to talk to our phones if they can't cryptographically verify that we have not "tampered with" them. We'll be refused service straight up unless our computers are straight up owned by corporations.

This so called "integrity checking" is meant to protect the corporations from us, not the other way around. It's so we can't do things like hack our way around their "policies".

Well, there are examples such as Yuh and Swissquote which are using Play Integrity API and also using hardware attestation to specifically allow GrapheneOS. The latter is in the process of implementing what's needed right now.

We also expect Google's Play Integrity API to inevitably be ruled as anti-competitive, which it is.
