  • The fediverse is already, by itself, designed to be a framework for this exact thing.

    The problems we have, and are always going to have, are that not all pieces of backend software have the same functionality. For example, you can already follow Lemmy communities and users from Mastodon, but not the other way round. If one backend implements some piece of functionality (e.g. upvoting/downvoting), then all backends that haven’t implemented it are going to be incomplete in how they can interact with it. It’s not possible to implement every conceivable functionality in all backends, that would actually kinda defeat the purpose of having different backends.

    As for your idea of “fediverse-wide SSO”: there already is an open standard for SSO called OpenID. Fediverse instances could be OpenID providers if that’s desired. But that’s still a separate thing from ActivityPub.
