If software doesn't want to run on your hardware because it can't make sure you're not tampering with it, why is it wrong for doing so? You're not necessarily entitled to the ability to run the software right? I understand the implications this has on ones ability to create custom operating systems is troubling (eg this could destroy desktop Linux), but at the end of the day I guess it is just a choice the developer is allowed to make. It's not like they distribute the binary with no strings attached.

And there are some real strong reasons why you benefit from this sort of ability, such as preventing folks from cheating in competitive games. I can't say that all uses seem to have good reasons to use it, but that seems like more of a vote with your wallet sort of situation. Perhaps the play store should also have stricter requirements on acceptable use of attestation and ensure they are upheld.
