This is sort of how Google’s Chat tool ended up rolling with the XMPP community. Their initial chat system was federated (this is pre-federation, but the concept was essentially the same) with the XMPP servers of the world. You could use their pre-hangouts Messaging app across the XMPP world.
Then, when Google was unhappy with how the XMPP standards were moving they defederated, replaced their entire protocol and stole the user base from the XMPP community.
