It's like we live in different worlds. The entire arc of technology over the past 30 years has been to centralize, collect, and then monetize. There are tons of systems that shouldn't be doing that, but they all evolve to end up doing that. We need a new version of Zawinski's Law: every company will attempt to monetize until they're selling user data.
That's literally why we have GDPR. This will be very illegal and the law itself specifically bans user identification with camera on top of the stuff protected by GDPR.
