For athletes whose visibility is pretty limited to fans of their sport, DTWS is a great opportunity to find a broader audience, which can translate into higher-paid endorsements. For reality stars, yes, a sixteenth minute of fame. For unknown actors on the way up, like Gilles, a good showcase. But for the already-arrived? Nope. Too many chances to make a fool of yourself, lose to a nobody or be less likable on live TV than you are in a carefully staged press or photo op.
