Furthermore, under the "businesses can do what they like" principle, there would be nothing stopping a business offering to ban anyone as a paid-for service. On the technical side of this issue, I am curious how MSG as to how acquired the reference images, and I wonder if they would try to pass it off as fair use. In fact, I am slightly skeptical that the identification was done via face recognition, as opposed to through the ticket sales chain, with face recognition being claimed as a cover. If using ticket sales information this way would present legal problems for MSG, I hope this possibility is investigated. (Nevertheless, face recognition clearly could be used this way, so that issue would still be on the table regardless of what MSG did here.)
