I think the only way will be the tech getting too useful for the complaints to matter. Currently it's only marginally useful. Otherwise this irrational reaction will continue. Would help for the tech to come from companies with less awful reputations.

Alternatively, maybe the solution will be some sort of device signature embedded into the video data at the hardware level so that videos are traceable to the person that recorded them.

To me the main annoyance is that XR glasses partially rely on cameras to enable things like 6DOF tracking and hand tracking. Having that use conflated with people trying to secretly record others is pretty annoying.
