Censorship in the West is a bit different. It is waged through the "free" mainstream media. Think of it as market share, where the MSM has 90% market share. It doesn't really matter what the other 10% think when they can be either brainwashed by partizan journalism or divided and made irrelevant. The main difference is that there isn't just one ruling party, there are usually two (conservatives and socialists) with their grip on power. If you don't align with them, you're irrelevant - unless they both screw up bigtime like it happened in France.
