    > If a company has an almost defacto monopoly and stops people from talking about something, it's effectively the same as a government doing it.

I would take it a step further and say that since the US Government has special relationships with many companies, they effectively become an extension of the government apparatus. In those cases, rather than letting government outsource themselves out from beneath regulation, we extend regulation as it pertains to government work to the companies doing business with the government.
