They're likely complying with the laws where they do business in this case. censorship? You bet! Government sanctioned censorship. They're a private company doing business in China. They're going to have to make a decision: Either subvert the 'man' or comply with the law. While i would choose subvert the 'man', I would not say i'm doing it because its legal. Different arguments. Also worth noting: These voluntary actions are also legal. They're also private businesses in the USA, and they are free to do this with impunity. One can always take their business elsewhere, or otherwise get information in other ways. They aren't stopping you from accessing anything.
