This article is one of the more thoughtful ones on this. I think Facebook is running up against human nature. Yes, humans are social, but we are also exclusive. Software that provides an outlet for the former but not the latter is betting against human nature.

Relying on lock-in to support these changes is hoping that the superstructure will compensate for removing a girder. It may work, but the fundamentals are against it. And there's a tinge of recklessness about it.
