That's really the paradigm shift - communities were self-organizing and self-moderating before. Now game publishers want to control all aspects of the online experience so they can sell you content and skins, so that means matchmaking and it means they have to shoulder the moderation burden.

This led to legit players that were just good being banned by salty mods, or cheaters that were subtle enough to only gain a slight edge not being banned.
And now, you have false anticheat bans. If you get banned from a server you can just join another server. (or even start your own!) If you get falsely banned from the game by anti cheat your money was in some sense stolen.
