The problem with the light is, it's incredibly small and dim, so is very easy to miss. Plus, people aren't aware of what to look for yet because they're not used to being around this "perv-vision".
I saw a guy at a sandwich shop with them and he was loud and bragging about them which was the only reason I knew he had them.
I'm honestly shocked they're allowed in Illinois being there's the "all party consent" law still in effect where any audio surveillance or recording needs to make all parties aware they're being recorded. Then add in the BIPA (biometric information privacy act) where you KNOW Meta is going to use face ID or facial recognition to tag or show the owner who's who.
