Is there a reason why all the services, that use the ActivityPub protocol don’t have a unified API?

None of the mastodon apps allow me to log in with a lemmy/kbin account.

Also none of the lemmy apps allow me to log in with a kbin account.

Even though kbin has both mastodon (microblogging) and lemmy (threads, communities) functionality.

Also, Pixelfed recently introduced “login with Mastodon”, but all it really does is just create a new user on it’s instance and copy over the mastodon followers and profile info.

Why can’t we just have one account to rule them all?

    ActivityPub has a C2S (client to server) API in addition to the S2S (server to server) API, it’s just that nobody cared about it to implement it. And because nobody implemented it nobody iterated upon it so now it sits as this underspecified (and unusable) state.
