"Publicly listed" is a rule not a law. So it means what MR says it means. In this case "listed" also means "available." They are not cheating you if they don't accept your much wider interpretation.

This is a classic example of looking a gift horse squarely in the mouth. MR has given you a free night and you want to parse the rules to gain further benefit. Get over it and show some respect and appreciation for the special recognition shown you. What does it cost and what is it worth to win the last dollar?
