Supreme Court Justice Clarence Thomas suggested that Congress could consider extending "Common Carrier" legislation to cover social media networks. I'm not convinced that would be an improvement over the current situation but it's an interesting idea. The telephone company doesn't censor which topics I can discuss in phone calls so perhaps other communication technologies should work in a similar way?

This completely ignores the history of why common carrier regulations were originally implemented.
Common carriers had such regulation on them because their infrastructure was a natural monopoly. The lone train line through the town. The single telegraph and telephone operator. The only trucking company operating that route.
It's not clear to me we're at the point that Facebook is the only real way for us to talk online. It seems like there's a lot of easy to access competition in this space.
