I think about this a lot. Lemmy fully deserves to have a lot of users, and a lot of users means a lot of opportunity to profit one way or the other, so the potential for profit-seeking behavior is there. So if we imagine a future where one instance has 500k users, it’s easy to imagine the owners trying to take it beyond the break even point and making it as profitable as possible. Anyone who puts themselves through the trouble of hosting an instance deserves to make a good living, but we don’t want predatory greedy policies.
The question is, how easy is it to migrate your account from one instance to the other? I haven’t tried yet
