From The Guardian, via A Glimpse of the World:
Google, the world’s biggest search engine, will team up with the world’s biggest censor, China, today with a service that it hopes will make it more attractive to the country’s 110 million online users.
After holding out longer than any other major internet company, Google will effectively become another brick in the great firewall of China when it starts filtering out information that it believes the government will not approve of.
Despite a year of soul-searching, the American company will join Microsoft and Yahoo! in helping the communist government block access to websites containing politically sensitive content, such as references to the Tiananmen Square massacre and criticism of the politburo.
