GeorgeSoros It would be good to know if the recording feature and others is prohibited by GOS. The link addresses software, but it doesn't seem clear if this could be a hardware feature.
These days basically all "hardware features" are implemented using software. Keyboards, mice, USB DACs, Bluetooth headsets -- all are controlled by software that controls them. Very little happens -- especially not complicated things like image recognition or voice recognition or talking to satellites -- without software.
On a smartphone, the camera does not spy on the user unless the camera app, or some other malicious software, uses the camera to spy on the user. The microphone does not spy on the user unless malicious software uses the microphone to spy on the user. The GPS hardware does not spy on the user unless malicious software collects location data from the GPS hardware and sends it to somebody.
Pixel phones contain "AI hardware", e.g., a TPU. But a TPU is not an AI. A TPU is hardware that multiplies and divides lots of numbers per second in certain patterns. If certain patterns of numbers are fed in, the result is image recognition, or voice recognition, etc. But the image recognition (or whatever) is a function of the software that picks which numbers to feed into the TPU in which pattern. The TPU itself is not an AI that is spying on users. The TPU does nothing (good or bad) without extensive direction by software.
Android phones running Google's OS have hardware support for waking up when spoken to (e.g., "Ok, Google"). But GrapheneOS ships without software to enable that function. The hardware feature is not a threat, because there is no software using that hardware.
