It's sad that this doesn't get the same attention as when Apple tried something similar. Google's not using PhotoDNA (a preexisting hash-based list). They're using flawed image recognition algorithms to try to recognize never-seen-before CSAM. Apple's proposal was actually far better for privacy than this; and though it was done on-device, it had a threshold of 30 images. Google is doing far worse than Apple proposed, and nobody seems to care.
