There were pedophiles, porn, extreme gore, cults, scams and a primitive notion of brainrot. Music and games (not that I played games, but honestly my mum thought that this is why I liked computers and what I was doing) were generally thought to turn kids into killers.

Computer users even in the best conditions (and not children) were looked at negatively- as if they were no life losers. The techbro thing, and the normalisation of computer use is a very modern notion.

FWIW I had the same exact situation as the parent, and heard it all from my mum. The computer was considered undesirable at best and actively harmful at worst.
