Deals shouldn't be the focus of our discussion. Instead, we should be afraid of the fact that facebook can wield the power of the social graph (which it owns) to create extremely valuable wholly owned subsidiaries. Most startups that rely on the network effect could be better implemented by facebook.
Does that make them a monopoly? If so, is it something we should fight? If the idea of a network-effect based startup benefits from a bigger network, we should all want them to own these ideas then, right?
