The National Union of Journalists (NUJ) is calling for a boycott of
Yahoo! because of its "unethical behaviour" in China.
Yahoo! has been criticised for cooperating with Chinese law
enforcement. It has given details of at least three people to Chinese
authorities who were subsequently imprisoned. The most recent of these
was Shi Tao who was sentenced to 10 years in prison for "divulging
state secrets" - he forwarded a government email sent to journalists
warning them not to report on the anniversary of Tiananmen Square
because it could encourage trouble.
