You're essentially carrying a video and audio camera that feeds to Meta --- and you're footing the bill for their data collection.

This was expected. Although nobody is objecting to the same thing which is already happening with dash cams in cars recording driving behavior and even crimes on roadways and in parking lots - - - I predict there will be instances of aggressive encounters in public spaces, especially in restaurants, where people who don't want to be filmed demand the folks wearing these glasses put them away, and if they don't, those who feel threatened rip them off the faces of those wearing recording glasses and throw them to the ground and stomp on them. To prevent these sorts of violent encounters that alarm and unsettle everyone inside, I have to support all restaurants banning them, notices posted at the entrance, and you get bounced out immediately if you put them on inside a restaurant.
