I don't remember an internet ever being "unsupervised" it was more that there were thousands of independent fiefdoms run by one autocrat and his minions. If you were in agreement with the ideas of that autocrat, it felt like freedom. If you weren't, you got banned and you found a different fiefdom with rules you liked, but there were plenty to choose from. Nowadays a few megacorps run those fiefdoms so it feels like there's less freedom because there's less options.
