IHT reprint an edited version of Rebecca Mackinnon's recent Yale Global article:

Are U.S. companies responsible when the Chinese government deploys their technology to stifle free speech on the internet?
 
Human rights groups want to hold such companies responsible for facilitating restrictive government policies. Defenders of the companies point out that by hooking China up to the World Wide Web, the companies have done much more to expand freedoms in China than to stifle them.
 
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.
 
Then the question is whether there should be consequences for companies found to be knowingly aiding censorship and political repression.
