Unfortunately this is unsurprising; with bad actors like Meta there are likely many potential "dark patterns" put in place.

I can imagine e.g. security risks involving sensor data exfiltration where accelerometers and gyroscopes etc are monitored to infer audio information. By covertly relaying and processing the collected data externally it would be possible to reconstruct sensitive information without direct access to the device's microphone.

It's not unlikely that they pull off something like that.

Meta and other pernicious companies and government bodies are probably employing many more, even worse and much simpler eavesdropping techniques in the wild.
