Cisco Systems built a security system for the Chinese government knowing it would be used to track and persecute members of the Falun Gong religious minority, according to the Electronic Frontier Foundation technology rights group. Falun Gong practitioners alleged the same thing in a lawsuit that a federal judge in Northern California dismissed in 2014. That case is being appealed, and on Monday the EFF, Privacy International and free-speech group Article 19 filed a brief that supports the appeal. The case highlights the risks technology companies take by selling software and hardware to customers around the world. Some of those customers may use the technology in ways that raise objections in other countries, creating legal problems or just tarnishing a vendor's reputation...“We have always maintained that there is no basis for the allegations against Cisco, and there is no merit to the case," Cisco said via email. "We do not customize our products in any way that would facilitate censorship or repression.”
