Zuckerberg said it himself: without the amazing monopolistic properties of the system as proposed, providing free access to everything would not be economically viable. Of course it wouldn't be economically viable, how could it be?

On the revenue side, Facebook doesn't monetize these users (yet), and it's a virtual monopoly in almost every market it's in. On the cost side, one bit costs pretty much the same as any other to serve.

Facebook doesn't actually bear the costs for the data here, btw.
