Ownership. Unless you have the technical chops to host your own server - or money to pay someone to do it for you - your existence is at the behest of your admin.
Shareability. I don't want to have separate identities for every app I use, e.g., one for Mastodon, one for Pixelfed, one for PeerTube, but I must. Each app is simply a lens over my graph, but I can't treat it as such. Maybe this is possible within the spec, but it's not apparent how that would work.
