Way to go Google! Now it is up to China to decide how they will respond. Quite a pickle for them.
If they concede to Google, who has stated that they will no longer filter search results, then unfiltered access to the Tiananmen Square incident will finally be available within mainland China. On the other hand, the notoriously prideful Chinese government can tell Google to piss off, and look far worse.
Either way, the good guys win one this time :-)
