Google didn't entirely pull out of China, they just terminated their product lines that were unsuccessful in China.
I was also just posting a fact that people have made the same calls for China, not my personal opinion about whether we "should" discontinue services with China. On that last point, I'm honestly undecided.
They did still redirect people to the Hong Kong search though. They didn't entirely pull out from China, just discontinued the Chinese search engine. And they did that because Google.cn was largely a broken service with a significant number of results being blocked by the Great Firewall. That wiki literally states all of this!
Google Search was never really what one would normally describe as a "successful product" in China even when it was at it's hight in terms of market share. It sucked and given Google still operate in China, have development offices there and actively promote Android (amongst other services), it's a real stretch to say that Google discontinued Search in China over ethical reasons. Search was just, like many of their services in the west that get canned, just not proving successful enough to be worth the hassle supporting. Which was my original point.
edit: Christ on a bike. I'm getting downvoted when even the citations backs up my statement. Googlers must have logged on for their morning dose of internet outrage.
