If that’s the case then what does Eugen Rochko do? Or is it like Linux where Linus Torvalds works on Linux every day but doesn’t actually own or control things that are based on Linux (such as Android)?

Is there anything that stops Elon Musk from buying Lemmy or Mastadon? Even if everyone were to migrate over to the Fediverse, what stops these websites from being bought as well?

This makes sense, thanks!
