This isn't TOR, though it's not completely unfounded that the definition of CSAM could be broadened in the future by legislators to include things that are, by current definitions, not CSAM, e.g. works of fiction that include scenes of abuse.

Already happened in Australia, in a recent case.

I don't know the exact details, but that sounds dystopian.

Yes, your copy of your operating system could also contain CSAM, I hope you checked every single byte just to make sure.

Please, let's be sensible and think about probabilities in the real world.

I think they were just meeting the original commenter where they already were.
