But those cameras aren't there because of the vending machine. That is just a convenient platform. This is about ads, and tracking, and data brokering. We had digital ad screens placed on the platforms at train stations in the Netherlands with a camera hole a few years ago, and the advertising company swore that those cameras would not be activated, for now, until the legal side was resolved, or until they could get away with it without anyone noticing.
It feels icky.
