Is Facebook really making the world more open?

According to its founder, and its mission statement, and the slogans that are emblazoned on its hoodies, Facebook exists to make the world a more open and connected place.

It seems strange that the company does the exact opposite. It denies users the ability to export their contacts, it has recently started hiding users email addresses. 

Facebook's strategy is simple, its to make the world a more closed place, where it is the middleman, where you need to go through it to connect with your friends, colleagues and even customers. Where it has aboslute, complete control. But that wouldnt make such a catchy slogan would it.
