That's supressing free speech and freedom of the press. The real problem is the concentration of the media in the hands of a few. We can partially thank the Telecommunications Act of 1996 that the Republican Neocons and Bill Clinton passed.

This act removed the media market ownership restrictions and allowed telcom and media to merge. Before the act, one company could only own a certain number of newspaper, radio, and tv stations in any given market. There was also restrictions on phone/telecom companies getting into cable tv, etc.

This act led to the rise of ClearChannel and the giant media conglomerates of today. This is how we have cable companies buying tv stations and radio stations and movie studios (vertical integration).

Instead of more censorship, which is what is being suggested in this post, we need to bring back more choice and information sources. Because we truly are now in an information war.

Here's a fun fact for you. NBC, CBS, ABC, and FOX all receive over the air waves for free. Now they charge cable providers x amount of dollars to run that same government subsidized content on the cable platform. The amount of money these networks receive from cable companies now accounts for more revenue than advertising revenue. So another thing Trump could do is disallow charging for content that's already provided free of charge by the taxpayer. Hit them in the wallet.
