I think it's sad that the core apps include Facebook and Twitter, but not a real instant messaging client (as in "I can install my own server if necessary", "end to end encryption", etc.) Instead of more client implementations for the same commercial services, the free software world should work on bringing the state of the art to free (as in freedom) tools.
No, this is not Richard Stallman speaking. I just want to keep my data on my own server, or at least have the choice to host it at a company in my own country.
Facebook Chat is just their private server of an open protocol (XMPP). Unless the client specifically prevents you from doing so, you should be able to use your own server just like you can with e.g. Pidgin.
Well, I have some unfortunate news for you: to my knowledge, not one single Facebook Chat app allows this. There is no market. It is beyond wishful thinking to expect Ubuntu to turn this around.
Exactly, there is no market for real privacy and openness, and it certainly is not in Google's or Apple's interests.
That's why I count on free software to close the gap. Free as in: free of corporate interests, no need to make money, no need to provide access to intelligence agencies. I pay for the hardware, and I pay to transmit data. But the data stays mine.
Well, it depends on whether they're planning to build a Facebook Chat app, or a Chat app that supports Facebook (like the previously mentioned Pidgin). The document is just a use case map, not a proposal for any specific application.
