If it's because of a "long history" they shouldn't have been invited at all.

To invite someone, knowing what they are, and to then un-invite them because of what they are, is idiotic.

Sorry, but they really screwed this one up. They should have never made the invitation, or made it without including a speaking engagement.

Agreed. The Hall of Fame may have lost their enthusiasm for the event after Kevin Costner turned down an invitation. They would have been better off just cancelling the whole thing.
