Given the historically proven record of China and its espionage, it should be the other way around. It is a part of their history and their culture.
Nortel? After the Chinese were done with them, Huawei and ZTE rose up as PRC military-backed entities.
US government contractors? The Chinese have been continually caught with their hand in the cookie jar.
Any company that deals with China? Expect clones if your designs aren't tightly controlled.
On the other hand, the accusations against the US rely on baseless allegations from a cowardly individual. The desire to preserve one's own life, through the trading of national secrets for protection, put the lives of US citizens at danger. Enemies changed their actions based on the improper and unlawful disclosures of classified material.
The only valid response to such demands from China is to turn up the heat on their actions. Huawei's banishment from the US and Australian governments was a good start in that respect.
It's a pretty bad troll. 3/10 at most.
But I really loved the part about "cowardly individual". I think it was the highlight of your troll.
Also, home of industrial espionage would be the USA.
