Hypothetically speaking I could envision activists printing out posters and stickers saying things to the effect of, "Smart glasses may be undressing and tracking your children." though I have no idea if such stickers and posters would get taken down or if that may lead to injuries. There could be t-shirt with a catchy logo that says something similar.

There have been spy-tech gadgets around for ages that can hide cameras in plain sight such as mini cameras that can be fitted inside a hat that looks like a decal. Mini cameras that look like a broach or shirt button. I think the difference is such gadgets have never been mainstream or popularized by a big tech platforms nor designed to integrate with cell phone internet connections into said big platform that is so tightly integrated with the government.

If everyone wears a smartglass it becomes easier for the creeps to hide. A tree in the forest.

and that you'd be considered a creep and probably questioned by the police if found with one of those, while we're on a path to be forced to accept people with smart glasses
