This reminds me of the days Gaim (now Pidgin) was playing catch-up with the Yahoo messenger protocol changes. I used to have entire days/weeks offline from IM because of these changes.

Fast-fwd 7-8 years, the same story, just different players. What's funnier is that WhatsApp actually uses modified XMPP software/protocol which should be open and free..

We get what we deserve.

Looks like we have come far away from standard federated XMPP. This is really depressing.

>should be open free

What are the license specifications of XMPP?

The protocol is an open standard, similar to HTTP. There's no license to speak of. There's many implementations of the standard, and those can have any license the developer wants, including making changes which break other clients.
