A federal lawsuit against Cisco was dismissed by the District court of Maryland. Cisco had been accused of assisting the Chinese government to censor, monitor and control online speech made by political dissidents.
The court found there were legitimate usages for the networking equipment designed and manufactured by Cisco, such as routing and passing internet traffics.
The case was Du Daobin, et al, v. CISCO Systems, Inc. et. al, 8:11-cv-01538-PJM.
