I think you've misunderstood. It's not an app problem. The problem is that it makes Free Software OSes unviable. The copy of Android you compile and install yourself - or your copy of desktop Linux where you upgraded the kernel yourself - will never pass remote attestation, and it gives both the attestation provider and software that checks attestation the ability to unilaterally shut out any OS they like with no workaround, even those that do pass attestation.

In a world of deeply untrustworthy Big Tech, and trend of governments, banks and other basic services needed to exist in society relying on apps and in the future, websites that use remote attestation, that is very troubling.

There are better ways of dealing with the bad actors problem, but Big Tech has chosen violence.
