It’s not that the people on vlemmy were “shown the door” everywhere else. It was merely the people who decided they wanted to choose for themselves which doors they would enter, and not be told by an admin they couldn’t enter certain doors. The instance I’m on now isn’t defederated with anything either, and if it ever does, I’ll find a new one that doesn’t. I don’t like being told which parts of the internet I’m not intelligent enough to decide for myself about how I feel. I can curate my own feed by simply blocking communities I don’t like, or by only subscribing to ones I do and browsing the Subscribed feed. I get burggit.moe and lemmygrad.ml and exploding-heads and all the other ones people don’t like, and if I see a community on any of them I don’t like, then it’s MY job to block it from my view, not an admins. I respect those who would like a more curated experience and there are instances for that, but don’t assume everyone who is in support of completely open federation is a pedo, nazi, socialist, fascist, or ANYTHING else. It just means they want to decide for themselves.
