The cynical underlying reality is that Facebook does not wish to appear heartless, but does not (yet) have the more subtle manipulative institutions that newspapers and TV stations have developed over decades or even centuries. They clumsily act in a politically correct manner, without proper institutional camouflage, and now they are being called on it. They will refine their bias, and make it subtler and harder to criticize, thereby becoming more like most other media outlets. Ultimately this is more of a social conformity story than a monopoly power dilemma. – Tyler Cowan
