More ownership over my data. Now I don’t really own anything I post on my Lemmy.world account but they also can’t stop me from exporting my subscription list and moving my account to somewhere else on the fediverse. And if I wanted to, I could port my account to a single user instance and I would actually own my local copy of the data (of course federation means I don’t really own the federated copies since it’s all public.

It’s more relevant on a platform like mastodon where I not only can export my follows but can port my followers to my new account if I move.
