The Internet giant's co-founder, Sergey Brin, 36, discusses his company's troubles in China and its controversial decision to pull up stakes and leave... Brin: ...[Our decision] is really opposing censorship and speaking out for the freedom of political dissent, and that's the key issue from our side... The hacking attacks were the straw that broke the camel's back. There were several aspects there: the attack directly on Google, which we believe was an attempt to gain access to Gmail accounts of Chinese human rights activists. But there is also a broader pattern we then discovered of simply the surveillance of human rights activists... When we entered China, we had hoped that we could really help move Internet freedoms there forward. And I think we were partly successful. [also refers to Baidu, Microsoft]
