> ActivityPub does have a migration story -- people move servers all the time
Correct me if I'm wrong (and in this case I would love to be), but you can migrate your account to a new server, but you have to create a new identity (ie profile URI) on that server. This would be fairly easily solved by servers allowing users to bring their own domain names. In the age of Let's Encrypt it's much easier to manage certs for many domains. They've known about this for 6+ years[0]. The fact it's not a high priority is concerning.
Unfortunately that's not a rough edge for me. It's a deal breaker. Especially in the scenario where your instance disappears overnight without helping users migrate.
Fortunately this isn't an inherent limitation of ActivityPub, and I'm hopeful we'll see implementations with better custom domain support in the future.
Overnight disappearance is bad, yes. Whether normal migration a deal breaker is personal of course. Having a slightly different attitude to your account helps. Don't get too attached to your identity and the archive of toots that builds up. The quality interactions are what make the Fediverse most enjoyable (imho), and those come along fine in a migration of followers/following. And people hitting your old profile, will see the redirection to your new location.
