Have you ever had the impression that special interests are much more interested in copyright violations than child pornography? Or that it might extend to memes that sabotages carefully crafted propaganda? I do have that impression a lot.
I don't step in the lowest parts of the internet hell, but I am also not very picky about it. I have never encountered child pornography in 10 years of almost pathological internet usage.
Scanning for DRM violations was one of the use cases mentioned in the article linked above.
I didn't know what CSAM stood for so I first though this would be the reaction to the security issues iPhones faced. Oh, silly me.
Additionally, by calculating hashes of media on peoples devices, you can quickly determine networks. A private image you shared with your friends? Unique hash and everyone that has it is probably in your network. That is aside from the issue that they would also just read your contacts.
