That's an accusation and implication. The Chinese strategy, which isn't entirely secret, is to use their hackers to get trade secrets out of firms in all kinds of sectors to hand to their own firms. Each time, their firms leverage those as a head start on their own products which combine their own innovations, labor advantage, and money from vast market in China. It's a proven model. Far as Cisco and Samsung, it's been clear Huwei has been knocking them off the same way.
Besides, what are you even questioning given that Huawei admitted they had and removed Cisco source code? Of course they robbed them. :P
"As to Cisco, after their fasco with the NSA I would not trust them at all for security."
Which is totally irrelevant to my point that cloners... especially Chinese cloners... will make knock-offs of a hardware product in any country that hurt that company's business if the product is worth it to them. The NSA collecting secret information to determine if you're a terrorist, felon, or threat to foreign policy != Chinese intelligence giving your competition your I.P. who then operate in your market with cheaper labor. NSA is a hypothetical threat for most companies whereas Chinese tech and labor market have been doing my country (U.S.) in for decades with many companies achieving parity or dominance in some sector through stolen I.P.. It didn't help that idiots running our companies put R&D centers over there to reduce labor costs. (rolls eyes) Such stuff is an existential threat to small, hardware providers worth cloning given what Shenzhen can pull off.
