I loathe FB and their policies as much as the next person, but the problem is that, as another commenter pointed out, FB is very much requirement for arranging events and communicating because of the social inertia. Sure, you don't need a cell phone either! Throw it out, just communicate with people on your land line! Okay.. that's a little tricky.. the world moves on without me. You know, you don't need a phone at all. Just communicate with people by pen and paper!
Of course all of this is doable, but it is absurd to speak in absolutes and ignore that if everyone around you is 'speaking a new language' you can get by just by keeping the old one. You have to twist arms or be less efficient. Remember, at the end of the day, no one really cares about the implementation details: I just want to be able to talk to my friends, organize social gatherings, and share information.
We/I care because we understand the privacy/corporate-control implications, but... where do we go from here?
