The republicans want Twitter, Facebook, and Google to stop censoring (incl. down-ranking, labeling, etc.) mainstream right wing views. If they don't act more neutrally, the GOP will attempt force social media to behave as a common carrier, despite the implications that has for spam, real harassment, and so-called harassment, such as religious people tweeting their sincerely held views.

This issue really boils down to how you view social media's monopoly status. Are they a monopoly or not?

In republican's eyes, network effects make these companies a natural monopoly. Others think that's wrong because other sites are one click away. And, because Facebook displaced myspace, reddit displaced digg, etc.
