Please don't say Mastodon or the Fediverse is "impervious to private take-over".
Remember when email was built to be impervious to private take-over, but now nobody can run their own email server because it got taken over by corporations?
Remember when the internet was impervious to private take-over because we had distributed routing and stuff, but now it's entirely taken over by corporations?
Nothing is impervious to greed and money. Don't be complacent.
