If someone bought every instance in the Fediverse, they would technically own the Fediverse.
No, they wouldn't. They'd just own some servers. And in the meantime, other instances would appear. To own the fediverse you'd have to completely control every web server in existence, halt production on new web servers and somehow find a way to make open source software licenses invalid, buy then patent, then remove all the existing fediverse software types, somehow repeal ActivityPub as a standard and then make it all illegal across the entire world.
