Many Internet sector companies that have operations in repressive countries violate the principle of the free flow of information. To take just a few examples: - Yahoo! censors its search engine in China and collaborates with the Chinese police so that dissidents and independent journalists can be arrested and convicted. - US companies Secure Computing and Fortinet sell filtering software to countries such as Tunisia and Burma that do not respect free expression. - The US company Verint Systems and its British competitor Silver Bullet sell equipment for tapping mobile phones to the Vietnamese police. ...The governments of democratic countries should regulate the activities of Internet companies to prevent this kind of abuse... Any new worldwide Internet regulatory structure should establish international standards in this regard.
