Given that modifying just a single bit in an image results in a wildly different hash digest, I think the risk is a little overblown. There are probably easier ways for authoritarian governments to figure out who's sending illegal content, like just taking somebody's device and looking at their messages.

It's a lot easier to tell vendor X that "in country Y list Z is the one that should be used when looking for CSAM", and then add some known Tank Man derivative hashes to that list and find out directly who to arrest.
