Microsoft and Apple enable groomers. they are platforms where abuse images are shown (despite telemetry being able to detect and stop it), they could easily detect someone using their OS to groom a minor but yet their hands are clean? come on.
Didn't Apple try to implement client-side CSAM scanning and then everyone threw a huge hissy fit over it? I mean the idea was flawed for privacy reasons but you cannot stop everyone without stripping all privacy from everyone.
I'm not actually pro-CSAM-scanning, I'm making a point that pointing the finger at a one-man-show website saying "he should have prevented this" is unfair because the whole tech stack could be attacked similiarly.
