let's share our conspiracy theories on this one...
Kai was out of shape, has a medical issue, other reason for not competing.
Demands so much he knows they'll deny it, misses deadline.
Other sponsors (one of them belonging to the current reigning champion) tell Kai to fck off, predictably.
Kai gets all the sympathy in the world, he's trending on facebook, his thread is crashing getbig, and the world sees him as the victim, for NOT competing in a show where competing was always automatically given to him.
his company will have millions of devoted new fans all blaming "the man" for holding down their athlete. Pretty brilliant.
