Amnesty International said some governments routinely imprison Internet
users, police chat rooms, shut down Internet cafes and delete Web sites.
Amnesty International has accused Sun Microsystems, Nortel Networks,
Cisco Systems, Yahoo!, Google and other companies of helping governments
repress free speech on the Internet and track down users.
"We are calling on internet users across the world to go to
http://irrepressible.info and sign a pledge calling on all governments
and companies to respect Internet freedom," said Amnesty International.
"Internet companies often claim to be ethically responsible -- these
pledges will highlight how their cooperation in repression risks making
them complicit in human rights abuses and damages their credibility."
