Does American government censor the Internet?
The American government doesn’t censor, simply because they do not rule America. In China, the government rules the media. In US, the media (or their owners) rule the government – hence there’s much less need for censorship. The US system is much more subtle and, in a way, far more interesting to study. If you really get into it you’ll start to see how meme’s and “spontaneous” events are carefully implemented.
