Google just did what for its own good.
The moment Chinese tnemnrevog refused google,the moment Chineses' future almost got lost.Chinese market is just a small piece in google's cake.
Google is honest and powerful,but it's useless for the tnemnrevog in countries like China,as some leaders in the Chinese tnemnrevog thought,it's stupid to trust anyone in political world.Well,this is right,but they forgot one thing important,google said no to the US government in the past.
I believe google may come back in the future for economic invasion,that's the purpose of capital
In fact,the time google chose to leave is more important than the event itself.As something is going to happen in Shanghai.
