You will note that the mute button is not a physical switch that cuts the signal from the microphone, but a soft button. It will probably do what it claims most of the time, but if Google for whatever reason wanted to secretly unmute it remotely, I have no doubt they could.
Wireshark? Sure, but what am I even looking for? They could be holding on to recordings in storage to send them later when the device is unmuted again. They could be embedding audio in encrypted form into other innocuous-looking packets -- I doubt a device like this is quiet on the network even when muted.
Until all the software is open source and auditable and the switch verifiably breaks the physical signal path to the mic, a device like this can never be trusted.
