Google is still the most open search engine in China.  In some way, Google is the Voice of America.  Should we have shut down VOA just because the other side decides to jam our signal?  By the way, I should have edited the end of my comment to say that it is devastating to the Chinese citizens in the short run and devastating to the Google shareholders in the long run since currently Google is getting less than 1% of its revenue from China, so shutting it down really doesn't hurt Google's bottomline.  In any case, I grew up in communist China and had lived on the other side until I was a teenager and I really appreciate the benefits that even an suboptimal communication channel would bring to the Chinese people.  The alternative is simply unacceptable.
