Assuming there was an active espionage investigation into the alleged actions of a foreign government, you can bet that only a handful of people at these companies will be even cursorily aware of the situation. U.S. surveillance and counter-espionage laws restrict who can be told about classified information or investigations. Only those who need to be in the know are kept in a very tight loop
I think that story is a total slander.
It says it's China military designed the chip. Wow
China military must be super high tech able to create such system on chip in such tiny area, it's chip design is capable to match top Western company standard.
Also, why they say it's PLA chip? Because that cannot be proven.
If it says it's China company then people can go on to comapby website to check for product information.
Blame it on PLA then nothing can be proven.
So, they create this story so nothing can be proven true or false definitely.
