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.

The barrier to entry has also dropped a lot and the market has broadened.

It's a bit like complaining that these days people just want to watch TV, instead of writing and performing their own plays.
