Its seems the chinese govt is pretty open (? maybe) about what topics are forbidden. In the US we are clouded in talk of free speech, but the allowable topics are ever shifting with events.
A lot of government censorship in "free" countries involves just not letting the media find out in the first place. What is happening in the Australian governments off shore immigration detention centers? We don't really know because they don't let the media in and they don't let the detainees have access to phones/internet.
