Lemmy (and by extension the fediverse) is theoretically more robust against powerhungry individuals because people can move to another server. But if users loose all their data (their liked / saved posts and subscribed communities) when moving to another server they are less likely to do so, which increases the power of the people who run the servers over the users of those servers.

So if there’s some time in the future I’d love to have a feature that is making it simple to “move my stuff”.
