Yeah, basically. It doesn't seem like people actually use CSAM to screw over innocent folks, so I don't think we need to worry about it. What Apple is doing doesn't really make that any easier, so it's either already a problem, or not a problem.
> And that making an existing situation even more widespread is also completely OK?
I don't know if I'd say any of this is "completely OK", as I don't think I've fully formed my opinion on this whole Apple CSAM debate, but I at least agree with OP that I don't think we need to suddenly worry about people weaponizing CSAM all of a sudden when it's been an option for years now with no real stories of anyone actually being victimized.
If it were to become a problem in the future, it could become a problem regardless of whether or not the scanning is done at the time of upload on device or at the time of upload on server.
