I mean, the obvious one is that they can revoke certification of a photo despite it being real.
The harder one is they can force apple to certify a fake photo.
the part that would be very hard but not outside the realm of plausibility, is that gov could force apple to introduce a bug in its pcc platform to link photos to the photographer in order to track and arrest inconvenient people. Apple says there are a bunch of protections against that but ultimately you are trusting apple to do it the way they say they are.
This entire system relies on trusting apple

It does indeed, and that is a fundamental flaw. but as has been discussed here, it is better than the alternative, which is no verification.
During the pandemic, I outlined a scheme for using blockchain technology for image provenance and authenticity tracking. The idea was that instead of any one entity assigning authenticity that it would be done in a crowdsourced manner and that the device would overlay a score whenever an image or video is shown to a user.
My assumption was that the desire of users to see such scores would force all manufacturers to implement this open protocol. But my approach suffered from chicken and egg problem, which Apple's does not.
That blockchain approach doesn't really solve the problem. The point is to have a chain of trust.
