Rebecca McKinnion has posted a must-read item at YaleGlobal Online on how foreign technologies are being used to censor the internet in China.:

Are US companies responsible when the Chinese government deploys their technology to stifle free speech on the internet? If the internet is going to change China in the long run anyway, how much does their complicity really matter?
…
According to ONI, it is difficult to believe that Cisco, Nortel Networks, Sun Microsystems, Juniper, and 3COM do not know how their products will be used by certain customers. There needs to be greater public examination of exactly how US technology companies are conducting their business. What do they know, and when do they know it? There should be consequences for companies found to be deliberately aiding censorship and political repression.
