I didn't say extremist I said toxic but really anyone who's poorly socialized will go where they're allowed, which in Lemmy terms means general catch-all instances with loose moderation like .world and .ml.
If they choose to migrate to another instance, it will likely be a more extremist instance with poor moderation that has been significantly defederated.
In theory this is how it should work, but in practice the toxic people tend to move to general purpose more laissez-faire places like .world or .ml, which makes de-federating and cutting off 30% of all users a difficult decision for anyone trying to have a community.
The answer is less centralization, but that can't be forced. beehaw.org (for example) made the decision to cut off .world and they are better for it. But they are a large-ish instance in their own right.
I'm surprised there's no fedi version of Facebook but I'm also sure as the fediverse evolves we'll see the return of personal websites but with activitypub-based social features.
There is so much wrong with that firehose of nonsense you just said I don't have time to correct it all. So I'll focus on this one point:
Bitcoin may not be run by "a single government" but it is run by a small group of billionaires. You're a fool if you believe widespread adoption of it can improve things for regular people.
Oh man, I remember guys like you, I almost always did the smart thing, didn't engage and muted another 30 days; but I'd be lying if I said I didn't feel a twinge of respect for the dedication to the craft.
It's not a single person instance either, it's just using your own domain in your handle.
