The big difference between this and all the other facial recognition happening is that people knew it happened. Walk into a fast food chain and take a look at all those cameras. Do you really think they aren't harvesting every possible insight from them? I can only guess what McDonald's could glean from recognizing every face and tracking time/place/order/how long you look at the menu and which items, etc etc. I don't know that that is going on but in the US with how little we have in privacy protections I must assume that they do everything I just thought of and way more. We need more people exposing what is allowed by law and pointing it out in big obvious ways, only with a banner below saying "We tell you this is happening. Corporations don't"
