Think about what Google did to email. SMTP is an open protocol like ActivityPub.
Now think about what Google did to XMPP, also an open protocol.
I bet your answer is "I don't know anything about SMTP or XMPP" and that's the problem, big companies "adopt the protocol" then after getting all the users onboard, they deprecate the open protocol using private APIs instead.
@Andres @TranshumanBlues @davidrevoy - Very good comment, thank you. There was a time when different messengers could communicate. What a great loss!
