We're not talking about gambling-as-addiction. We're talking about gambling as big players paying participants to throw fights, paying referees to call shots, and the players are the real world and the referees are journalists.
What makes you think this is not "gambling-as-addiction"?
It seems to me that these players, big or small, either have too much skin in the game or are compulsive gambling. To me the threats only make sense in that context.
