For AR you need to be recording. If you are recording, it is being sent to Facebook servers. You accepted Facebook's terms and conditions, not me.

If you don't want to be punched, you should advocate for laws that make the glasshole glasses ugly through non-avoidable methods of detecting if the glasses are recording.

For example by requiring every glass hole glass to have a physical cover that physically covers the view of the camera, and it should be a bright color to easily see if it is covering the camera or not. The contour of the camera should be painted with an equally bright color, contrasting highly with the cover. So you can easily see if the cover is covering it completely.

A led that turns on when recording is not enough, it's very easy to remove a led from a device.

If you want to not use glass hole glasses for evil, you should want it to be mandatory for other people to see if you're using it for evil or not.

No, I am not giving a pass to government and corpos. But people recording others in public are henchmen of the very same fascist governments and yes, you deserve an elbow to the face if you record ANYONE (in more detail than within a large group of pedestrians) in public EVER without their explicit consent. Because you are - at least in civilized countries - violating privacy laws with the expectation that no one will sue you for it.
