I meant put it in the agreement with the host site when the equipment is provided. Then the site owner can figure out how to enforce it... if enforcement is what Tesla wants. Many of the sites I've been to have no such signage at all. Well, I simply took that to mean Tesla is the manufacturer of the EVSE. Just like ChargePoint and ClipperCreek put their names on their devices. There are Chevrolet Voltec units in a number of locations that are open to vehicles from other makers too (not that they're much use to Tesla owners at 15 amps max).
