Maybe half of HN is too young to remember (or old enough to have forgotten?) but when cell phones with cameras were becoming mainstream, there was media panic over them too - people could be discretely filming in bathrooms, locker rooms, etc. There were even a few high-profile salacious stories where people did use their phones to film inappropriately.
And then we collectively decided that having cameras with us was generally beneficial and rarely harmful, and people realized that creeps who wanted to hide hidden cameras could already do so, and we all kinda moved on with our lives.
I can't leave my house without being on a dozen Ring cameras, Flock cameras and probably a handful of satellites, along with devices tracking Bluetooth and WiFi IDs every time I enter a store or a cop car drives by or having my license plate scanned by passing tow trucks. Drawing the line at glasses seems pretty arbitrary.
