Glass made you look like an asshole. If people had a problem with insane surveillance, they would only use Pinephones with the hardware switches, and then put them in faraday fabric pouches and bags. (This is how I use my cellphones — phone goes in the pouch, and then goes in my Silent Pocket backpack.)
Really, there’s not much difference in surveillance hazard between the glasses and a normal cellular phone. Google glass just looked retarded.
