The way this instance is managed has been decided already and you don't agree with it, it's that simple. There's no discussion to be had since you're in favor of removing a right the admin gave the users (voting to defederate an instance). Take your pick, there's plenty of other instances to choose from and worst case create your own with your own rules.

And no we're not having a conversation about the future of the fediverse since you're expressing an uninformed opinion because you don't understand decentralization. Deciding the future of the fediverse would require centralization, the whole point is that each part can go in whatever direction it goes, no one can decide how the whole thing should work. If that's what you want then go back to Reddit and apply for an admin job, then you can discuss with people who have power over the direction a whole semi-decentralized system goes.
