Regardless of what Apple does, law enforcement must always manually review suspected CSAM before requesting a warrant based on it. So the idea that you could SWAT someone with some hash collisions on innocent images is just not possible. At most you could maybe temporarily lock someone’s iCloud account. But again, the collisions would need to be multiple and all look like CSAM at reduced resolution. In general, it seems not correct to think about NeuralHash like SHA or RSA. It’s not a cryptographic system and collisions are not a one-step endgame.

The one on Ousmane Bah really frustrates me- not only was he on a date at prom during the theft, he was in another state! "Nothing to hide" does not mean "nothing to fear" and allegations (even false ones) of possessing CSAM will ruin lives. At the end of the day, what it really comes down to is trust; personally, I do not have enough faith in due process to not ruin innocent people. But I'm just some guy online, I will readily admit I don't know anything about anything.
