That's a good point. I'm guessing that people calling for a "hardware switch" implicitly mean one that cannot be overridden by firmware.

I.e., a traditional switch inline on the circuit(s) connecting the camera / microphone to the rest of the system.

On MacBooks Apple says their microphone disconnect is "done in hardware alone", so it might be that closing the lid disconnects something physically.
