OoenID Connect is different. Its basically just OAuth2, and google/fb require the ap developer to register their app with google/fb in order to authenticate users.
Whcih is pretty bad for both developers and users, as a user I cant run my own identity provided and as a developer I have to spend time setting up accounts with ever identity provider i wish to integrate.
Original OpenID just let me as a user use a URL as my identity, so I could use any identity provider I wanted, including running one myself.
EDIT: There is a specification for dynamic client registration but nobody implements it as far as I've been able to tell.
