How is this proliferating csam?
Sharing it with people and companies that it wasn’t being shared with before.
Also, how do you expect them to find csam without having known images?
The same way it is now: people reporting it and undercover police accounts. People recognise it.
without having someone look at every picture on someone’s harddrive
If it’s going to get used as evidence in court a human will have to review and confirm it. I don’t think “Because the AI said so” is going to convince juries.
The only reason to be against this is if you are looking at CP
Or if it’s you or someone you love who is in the CP. Having further copies of it on further hard drives, whether it’s so someone can bake it into their AI tool or any other purpose is wrong. That’s just my view though.
I’m always surprised at how devious this windows spyware is. 99% of people would probably just accept to share all their data but that’s not good enough; MS has to try and squeeze out every last drop.
