Who do you think is doing the CSAM? It's the criminal organizations and the terrorists and the Russian hackers, obviously.

Nobody really cares what the excuse du jour is because everybody knows that's what it is. Authoritarians want to build a censorship apparatus to use against the public, but if they say "we want to spy on our political opponents and censor people who disagree with us" then nobody would support it, so instead they say "we have to get the pedos and Putin" even though that's 0.5% of what a system like this would actually be used for if implemented.
