This has happened with every single federated platform, and it can’t be solved with technology because it’s fundamentally not a technology problem. People want to be where other people are, so once the community reaches a critical mass it inevitably degrades into the same sump of mediocrities and their rules as everything else.
If you find yourself on the outside, it might just be that you're the village idiot. Before SoMe platforms like twitter, facebook and other places without local moderation the village idiot didn't have much of a voice either.
But the fediverse? Can't count how many times I've seen instance admins hold their users hostage in bitchfights over the Israel/Palestine stance of other instance admins.
Email is probably the closest to anarchy. If you could get people to use it for group communications, every user could decide who they include in their "reply all", which would probably lead to absolute chaos.
However, I do feel internet communities were better when they were smaller due to being special interest driven and self-policing. People wore different hats according to the community they were engaging with.
not neceessarily true, see Matrix where it pretty much doesn't matter where you are
It didn't happen with the internet itself. You still can avoid Facebook and co. and happily discuss things on HN.
And with the email, it is much less serious than people assume. I do not use gmail or MS and practically nobody I talk to does.
