It's good for Google because they can say they upheld their values, and it's good for the Chinese government because now they have one less external factor to manage in their control of information. Perhaps there is more to this picture than I am seeing but that has always been my view
I don't see how they could have stayed in China and not been involved in things that are truly evil. When the government phones you up and tells you to hide search results related to babies dying from diluted baby formula (yes, this happened), could you in good conscience tell one of your engineers to add that filter? How could a company like Google possibly retain good people when they have to ask them to do the bidding of such an evil government?
Yes I agree, this is an angle that actually came to my mind after posting my original comment. At the end of the day there had to be Google engineers in China doing the job, real people actually implementing censorship. So if Google being in China meant that employees had to be involved in inhumane acts, I'm not surprised they would leave.
