Facebook itself is already a bunch of powerful people - the people who make the decisions about how content is served to users.It's already a centralized source of power. Facebook already exercises this power by deciding how to determine what users "want" to see, i.e., what Facebook thinks users want to see. I'm not sure how you could claim that individual Facebook users have much power at all. What they see is totally determined by the platform.
