China or any government adding collisions would be to use Apple's system as a dragnet to find users possessing the offending images. The way it would work is the government in question would submit legitimate CSAM but modified to produce a collision with a government target image. Looking at the raw image (or a derivative) a reviewer at Apple or ICMEC would see a CSAM image. The algorithm would see the anti-government image. So Apple scans Chinese (or whoever) citizens libraries, finds "CSAM" and reports them to ICMEC which then reports them to the government in question. Every repressive government and some notionally liberal governments will eventually do this. It likely is already happening with existing PhotoDNA systems. The difference is that's being used by explicit sharing services where Apple's new system will search for any photo in a user's library regardless of it being "shared" explicitly.

If Apple finds that a particular hash is notorious for false positives, they can reject it / ask for a better one. And they’re not scanning your library; it’s a filter on upload to iCloud. The FUD surrounding this is getting ridiculous.

  Look, I said it in another post, it is not Apple’s job to act as an arm of law enforcement. The same way it is not either of our jobs to be vigilante sheriffs and police the streets. We’re talking about a company that makes phones and computers, and sells music and tv shows via the internet. Does that matter at all? How about this. All car manufacturers must now wirelessly transmit when the driver of the car is speeding immediately. How about that? Let’s just go all out and embed law enforcement into all private companies. This is fascism, the merging of corporations and the government.

    It becomes their job when you ask them to host your images on their property. If you don’t, then there’s nothing happening.
