The tl;dr is that despite this man ultimately having his name cleared by the police after having his entire Google account history (not just cloud) searched as well his logs from a warrant served to ISP, Google closed his account when the alleged CSAM was detected and never reinstated it. He lost his emails, cloud pictures, phone number (which losing access to prevented the police from contacting him via phone), and more all while going through a gross, massive invasion of his privacy because he was trying to do right for his child during a time when face-to-face doctor appointments were difficult to come by.
This should be a particularly salient reminder to people to self-host at the very least the domain for their primary and professional e-mail.

The google one actually does try to detect new ones and there are reported instances of Google sending the police on normal parents for photos they took for the doctor.
Pick your favourite other example of when Apple and Google have faced roughly the same problem as each other, and hold up their respective solutions next to those in the example of CSAM scanning above. I bet they'll look similar.
