Does it really? As I understand it, the thing is pretty one-sided. Who manages and governs the collection of 'hashes'? If it's law enforcement there's no collusion needed. Also, someone can just text you such a photo, or some 0-day exploiting malware (of which governments have a bunch) would plant one on your phone.

All of this would happen after you're arrested, labeled a pedo and have your life turned upside down. All of which can be used to coerce a suspect into becoming an informant, plead guilty to some unrelated charge or whatever. This type of thing opens the door to a whole new world of abuse.
