You can still hack someone's phone and upload actual CSAM images. That exposes the attacker to additional charges, but they're already facing extortion and all that anyway. I don't understand the "golly gee whizz, they'd have to commit a severe felony first in order to launch that kind of attack" argument.

Don't know why this hasn't already been used on other cloud services, but maybe it will be now that its been more widely publicized.
