Will they only be blocking Microsoft, or will they shut off federation completely? I have an account on the FSF's XMPP server and I can talk to people on gtalk.

Will they only be blocking Microsoft, or will they shut off federation completely? I have an account on the FSF's XMPP server and I can talk to people on gtalk. If they are shutting off federation completely, then they are just making a walled garden for themselves and using the Microsoft situation as an excuse.
