redletterdave (2493036) writes "Facebook owns virtually all the aspects of the social experience—photos (Instagram), status updates (Facebook), location services (Places)—but now, Facebook is transitioning from a simple social network to a full-fledged technology company that rivals Google, moonshot for moonshot. Yet, it's Facebook's corporate control of traffic that leads many to distrust the company. In a sense, people are stuck. When the time comes for someone to abandon Facebook, whether over privacy concerns or frustration with the company, Facebook intentionally makes it hard to leave. Even if you delete your account, your ghost remains—even when you die, Facebook can still make money off you. And that's not behavior fit for a company that's poised to take over the future."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
