Why they shouldn't be allowed ---
1.The glasses have cameras and microphones capable of recording people nearby often without their knowledge (e.g. the recording indicator can be subtle or blocked, “GhostDot” stickers are being sold to block the LED indicator light so others won’t see when recording is happening)
2. As I remember Meta has changed its privacy policy so that voice recordings are stored in the cloud (up to one year) and “Hey Meta” voice-activation with camera may be enabled by default, meaning more frequent analysis of what the camera sees to train AI models.
3.The possibility that anytime someone might be recording you wearing glasses that look like ordinary sunglasses can create a chilling effect: people may feel uneasy, censor themselves, avoid public spaces, etc.
