In the wake of Google's decision to stop censoring their search engine in China, co-founder Sergey Brin both called on the US government to fight Chinese censorship and called out Microsoft for continuing to censor. Danny Sullivan cries hypocrisy:

Google surrounded [its decision to enter China in 2006] with all types of statements that censorship was really something it was doing to help a large population find good, non-politically sensitive information that wasn’t subject to censorship. [...] But bottom line, it was still a business move, to me. If Google just wanted to help people in China get good information, it could have spent the past four years helping to construct ways for people in China to bypass their government’s firewall. Or the past four years arguing that the US government and US-based businesses should follow its lead in staying out of China.

John Hudson rounds up more commentary. Fallows has been all over the story. Here he interviews David Drummond, Google's chief legal officer:

I then asked Drummond about something that has always puzzled me. If the original occasion for the shift of policy was (as generally reported) a hacking episode, why did it lead to a change in the censorship policy? What's the logical connection? He explained the reasoning in a way I hadn't seen before.

His partial reply:

[The hacking] was almost singularly focused on getting into Gmail accounts specifically of human rights activists, inside China or outside. They tried to do that through Google systems that thwarted them. On top of that, there were separate attacks, many of them, on individual Gmail users who were political activists inside and outside China. There were political aspects to these hacking attacks that were quite unusual. ?That was distasteful to us. It seemed to us that this was all part of an overall system bent on suppressing expression, whether it was by controlling internet search results or trying to surveil activists.
