> Not to mention that most people consuming CSAM are not technically savvy. It is known that such material goes through mainstream messengers.
The reason is because it works. They're not stupid - they can use signal.
The reality is that the privacy options not only exist, they're really good - often better and easier to use than the mainstream stuff.
They will just pivot to other tools.
> How do you contact children on mainstream messengers if you can't use mainstream messengers?
The scanning just doesn't include contacting children - it includes CSAM. Talking to kids isn't CSAM. You're talking about something else altogether, and something which is purely hypothetical.

My understanding is that they are not only talking about having a list of hashes (of illegal images), but also having some kind of machine learning. And they are not only talking about scanning images, but text, too.
I don't know what you expect them to report when scanning conversations with machine learning?
