the powers that be must never be allowed to join the fediverse
How are they not allowed? How is it checked, how prevented?
As I see it, they can freely use the code, freely set up instances, freely create user accounts on their own or other instances, with 'independent' users, employees or bots.
The only thing stopping them is the current fediverse's insignificance. We're just not tasty enough, yet. But if we become, how could we disallow them from joining?
