As a linux user if 25+ years, you're off on a bad foot with me from the beginning.

But if you like consolidated power, the fediverse is just not the place for you. The whole point is that we can't let things get too big, because that draws attempts to takeover the userbase. There are already organized efforts beginning on Mastodon to mass defederate from any server (maston.social) that get's to 51% of the total userbase because it would be an existential threat to all of ActivityPub if that happened. You're basically asking starfleet to please ignore the prime directive.
