I think they used to literally sell routers with pirated versions of Cisco IOS. https://www.networkworld.com/article/2223272/cisco-subnet/60-minutes-torpedoes-huawei-in-less-than-15-minutes.html https://www.networkworld.com/article/2223272/cisco-subnet/60...: > Folklore within the routing and switching community was that Huawei stole router product secrets from Cisco, down to the chassis, IOS and all the way down to the spelling errors in the manuals. Many have said it for years, but 60 Minutes put it on worldwide television tonight for everyone to know. Cisco did file suit and it was settled out of court, so we will never know what really happened. But Huawei did it, they know it, we know and Cisco knows it. Otherwise they would have never settled the court case.
