This is more insightful than the article. The problem isn't optimizing for the "community" as the article seems to think. The problem really is that what people think they want and what they actually want are opposed. Facebook faces the same problem.
I think the unfortunate endgame here is legislation that will require what people think they want (e.g. privacy, absolute control) at the expense of some things they actually want (e.g. frictionless social interaction, simplicity).
(To forestall some argument: Yes, I realize that privacy/social interaction and control/simplicity are not always mutually exclusive. However, there are cases where they interfere with each other, which requires compromise.)
