I always hate seeing this argument. Using back of the napkin calculations, that means Google is getting out of China because it's down to 50 million users there. I guess we should expect them to be leaving Canada soon, since they only have about 19 million users here. Not to mention that the number of internet users in China is growing by about 80 million people per year at the moment according to the world bank, of which Google was presumably getting their 17% as well.
