We will have to agree to disagree on this :-)
This is probably the main reason why the NSA runs its own fab operation.
The devices so engineered would not appear to be able to receive any sort of a signal or react to such a signal. But
remember that the NRO sats have 350ft dish antennas and can
generate a very brief data pulse of staggering power. It would not take much to detect such a data pulse. As for the receive ability of those sats they can get a whopping signal from something far less powerful than the part 15 emissions from commercial electronics. A lot of gear must have unsuspected 2-way data ability.
As for experts being able to discern whether a massively complex piece of hardware has any ‘extra’ functions... it would be a difficult chore to get the silicon wafers out
and pore over every possibility...there just ain’t enough time in the world.
The world is just filled with chipped devices of all sorts. I worry about what might be going on inside Chinese ICs.
I play with embedded systems mostly.

Given all the other things china is known to have been working on (like capacity to hold 25% of world internet traffic without a problem if they want to reroute), I can only believe they have all kinds of nasty stuff in places that it will get into routers, switches, and pc’s in general. This ignores what they can do with our electrical net if they decided to shut out some lights.
Unfortunately, they plan way, way ahead and I think at some point it will be evident that the US is checkmated before anyone ever fired a shot.
