Actually, the title refers to it as "bias" rather than "censorship". "free market" is a larger concept than "bias", although you can be biased while still operating within the context of a free market. Still, censorship doesn't have anything to do with the government, although the U.S. explicitly forbids government censorship.

You mean bias like Rush Limbaugh or FoxNews bias? Where other ideas are not only never presented, they are openly mocked?

And that happens mind you, on the PUBLICLY OWNED airwaves and spectrum....

"airwaves and spectrum.... "

If we really start considering media, a lot of taxpayer money worldwide went to broadband Internet infrastructure, so Twitter and friends do not play on a completely private field either.
