You were not going to be able to use those apps anyways, so what does it matter to you? I, and I suspect many, agree with the purpose of attestation. The problems around it are strictly around establishing good ways to teach apps who they should trust, not around attestation itself. By putting your head in the sand, you'll never improve the situation.
> teach apps who they should trust
Ah, the apps^Wgovernment (look at that page, most of it is government IDs) should be able to discriminate against me for daring to assert control over my own device. And GrapheneOS is saying:
Hey government! We pinky promise to oppress the user just the same, but even more securely and competently than Google/Samsung!
> what does it matter to you
It shows that the developers maybe don't fully have your best interests at heart?
