I reject the premise that CSAM scanning is a solution to anything, especially if the goal is to E2EE encrypt the rest of the photos.

My understanding from following this debacle is that law-enforcement don't have resources to investigate everyone who just have CSAM they focus on people who match and have other photos of novel abuse they can track down, and here they will only get an account name and a list of 30 CSAM photos the user had.

All this system will do is drive up Apples numbers on a "total child abuse found" scoreboard and do very little to help any actual children in need.
