There's the Fediverse sphere of platforms that largely fit your ideals but fragmentation is a glaring problem that prevents it from much wider adoption.

Any centralized platform where data is hosted is going to cost an obscene amount of money to operate once it gains traction. So they need to find a way to monetize it in order to keep the lights on. Throw in some venture capital and you've got yourself yet another startup that thinks they can scale infinitely.

My biggest fear is Discord gating old convos behind a paywall like Slack. Discord doesn't do that because it is still technically a different product from Slack, but should monetization drives intensify I'm afraid that'd be one of the easy channels they are going to take a look at.
