> for me, when both Facebook and Google rejected Jabber/XMPP federation :(

I agree with you in principle, but this is only half-true. You're right that Facebook's XMPP was always just a gateway into their proprietary messaging system, but Google did support XMPP federation. What Google did not support was server-to-server TLS, and thus it was “us” who killed Google XMPP federation.

In late 2013 there was an XMPP community manifesto calling for mandatory TLS (even STARTTLS) for XMPP server-to-server communication by a drop-dead date in mid 2014: https://github.com/stpeter/manifesto/blob/master/manifesto.t...

"The schedule we agree to is:

- January 4, 2014: first test day requiring encryption

- February 22, 2014: second test day

- March 22, 2014: third test day

- April 19, 2014: fourth test day

- May 19, 2014: permanent upgrade to encrypted network, coinciding with Open Discussion Day <http://opendiscussionday.org/>"

Well-intentioned for sure, but the one XMPP provider with an actual critical mass of users (Google Talk) remained non-TLS-only, all Google Talk users dropped off the federated XMPP network after May 2014, and so XMPP effectively ceased to matter. I'm sure Google were very happy to let us do this.
