Googles corporate mantra is "Don't be evil". In their Chinese operations Google has censored the web at the request of the Chinese government.

In 2006, in testimony to the US House of Representatives, Google executive Elliot Schrage said:

The requirements of doing business in China include self-censorship – something that runs counter to Google’s most basic values and commitments as a company. Despite that, we made a decision to launch a new product for China – Google.cn – that respects the content restrictions imposed by Chinese laws and regulations.

Late last year Google was the target of a sustain cyber-attack. They are now trying to decide what they will do:

These attacks and the surveillance they have uncovered--combined with the attempts over the past year to further limit free speech on the web--have led us to conclude that we should review the feasibility of our business operations in China. We have decided we are no longer willing to continue censoring our results on Google.cn, and so over the next few weeks we will be discussing with the Chinese government the basis on which we could operate an unfiltered search engine within the law, if at all. We recognize that this may well mean having to shut down Google.cn, and potentially our offices in China.

Google let dollars get ahead of their mantra, and that came back to bite them. Stay true to your mantra, Google.
