Networking equipment vendor [Cisco Systems] has been accused of helping the Chinese authorities snoop on, discriminate against and violently suppress the religious group Falun Gong…The Electronic Frontier Foundation (EFF)…has filed a request to submit an amicus brief in a US District Court in California…It asks the court to let the case "Doe vs Cisco Systems" go ahead...“The central claim…is that Cisco purposefully customised its general purpose router technology to allow the Chinese government to identify, track, and detain Falun Gong members."…The EFF alleges that Cisco was asked to customise its kit so that the Chinese authorities could pick up Falun Gong 'signatures' and enable the logging and monitoring of traffic patterns…[It]…alleges that Cisco knew about this customisation, knew that it would be used to repress the Falun Gong, and still marketed and supported the technologies "towards that purpose"…Cisco has declined…to comment on the views of the EFF and its lawsuit.
