Fifteen years ago the Huawei router manuals we were given for a project we did in Indonesia still had the Cisco logos on them. No kidding. There are hundreds of technology companies in China that outright stole American intellectual property and that now compete with our companies that created that technology. The government actively encourages it, but will never admit it.
US companies gave (or let Chinese companies steal) our technology. We should be holding their feet to the fire. Huawei probably made CISCO’s own routers under contract.
