@Flick The "migrate" function is a tacked-on feature with very poor UX. You have to go through a rigorous process to do it, and it doesn't always work. You can't migrate your posts, just followers. The domain NEEDS to be online for it to work, so it won't work if the domain gets seized or you get banned. Typically the people who need to migrate most aren't able to do it. NoAgendaSocial was a best-case scenario, and they still lost a lot in the move.

However I'm not denying this is a social problem. It's a social problem that can be solved through technical means, by letting users sign in with public-key cryptography, instead of having a single website control their account.
