A college is removing its vending machines after a student discovered they were using facial recognition technology

This is a most excellent place for technology news and articles.
I think a big question here is whether or not this feature of the machine was disclosed to the university when they were installed. It's one thing for the university to place its own security cameras that it has control over, but if a third party is placing surveillance devices on the property they should be giving very clear written notice.
