> i can also export all my followers, so when i join a new instance, i can direct message them all and let them know i've moved If ActivityPub had actually portable identities, you would be able to move instances without losing/moving your handle. You as an user might have moved servers, but your identity did not. How can we make an analogy? Let's say that you want to have a domain and you are hosting it on some cheap VPS provider. You just take your data, upload to their server and point the domain to their IP address. Let's say that six months later the cheap VPS goes down and you completely lose access to the server. You want to move. What do you do? You sign up to another VPS provider, upload your data (assuming you have backups) and you simply change the DNS to point to the IP address of the new server. If you want to do that anything like that with ActivityPub, you can only do it at the server level. If you are a "mere" user on instance mastodon.one you do not own, you are at the mercy of the admin. You can not take "genewitch@mastodon.one" and use it as a handle anywhere else. Conversely, you can not go to mastodon.social and sign up with your own domain or any other method of authentication. The only way they can serve anything for you is if you use the handle they assigned you. With ATProto, identity is based on DIDs (decentralized identifiers), so you can change your PDS without having to change your identity. You can have a handle under your own control and tell Bluesky to host it for you, and you don't need to ask permission to them in case you change your mind and decide to move elsewhere. |
