Why does yahoo support censorship in china?  which caused the arrest of a journalist?:
What is their choice really?  Either they do what China tells them or they offer nothing to the people there.  There is no way for them to improve conditions for the people of China if the government blocks and removes them?  Better to sacrafice and be seen then not sacrafice and be eliminated.  

People think there is censorship and a lack of privacy here; have no idea what freedoms they enjoy compared to the people of China.
