Any plan to decentralize Facebook will end up in a disaster as Facebook shareholders would never want monetary gains to be shared with it's users. The corporate finance mantra goes "The only objective of a corporation is to add value to it's shareholders". So, Facebook's talk about decentralizing power is merely a lip service and there are hidden agendas behind it!
