Johannes ErnstI have a comment here, though: there is nothing in #activitypub or any other relevant standards that says that #fediverse software needs to allow you to take your followers from one instance to another. In other words, the #fediverse does not actually promise anybody that they can take their followers!
(Maybe it should. I sure would like that. Some apps allow you to do that. But whether eg #threads ever implements it is entirely up to them)
