Some day you should take time to read those 5,830 words: it’s Facebook that owns the rights to do as it pleases with your data, and to sell access to it to whoever is willing to pay. Yes, it’s free to join — but with half a billion of us now using it to connect, it’s worth asking ourselves how far this “social utility” (its own term) is really acting in the best interests of society.

Yep.
