Hell the crazy things I used to do to connect to the internet after my mother went to sleep. She didn't wanted me using the internet because of phone charges so I secretly got into the roof to strip the phone wire bare and connect my own hidden cable that I would unroll and route it to my room to connect to my modem at night. YES part of it was to watch porn and download mp3s and roms. No I wasn't of legal age. Did my life got ruined by this? Well I'm an IT engineer now so arrive at your own conclusion.
I think this current hysteric moral panic is definitely being pushed by a lobby of a nascent AI industry that wants to create a problem for their surveillance tech solution. Its a big grift that aligns with incentives of power hungry politicians and data hungry tech giants.
