You listed twitter as a "proof" that you have alternatives, as an example that FB is no monopoly. I agree that Twitter is quite successful and big. In spite of allowing pseudonyms? White pages don't apply. No idea how these work over there, but here they are a service to find a phone number - and sell a couple ads. You don't communicate via White Pages. In fact, you'd only use those to find people _that you usually don't communicate with_. And then _move the conversation to a different medium (phone)_. Facebook is not related. It's not a simple register. It is not the same thing. It's like comparing the hand-selected early Yahoo! link collection with the current Google, including Search, GMail, GTalk, G+.
