official of Google said, So Google is sharing information with people in hope to get support against Chinese tactics of censoring the information and spreading message of freedom of speech on internet.
I feel Google is trying to create some pressure on Chinese government so government stop censoring the information on internet and allow freedom of speech on internet.I understand Google not at top in Chinese market but, they are smart enough to understand that quitting Chinese market will not make them top in china.Leaving the china cant be a business decision as it not make any sense to stop doing business if you are having 31% stake in market.Only reason could be they really wanna free internet.
