I don’t think C2PA’s goal is to completely prevent this type of thing, but to make it hard enough to stop low-effort attempts.
This, like DRM, will probably be an arms race, and future solutions will look nothing like what I described.
But then again, the spec has been out for more than a year, and I haven’t seen anyone big bothering to implement it. Maybe it’s a flop already.
