Not true at all! Their charter is for entertainment entity, not a sports league.You do not understand the law
You grasp some notion about entertainment and make up some theory
IF they get caught fixing, they are criminally liable
Ask a lawyer I have spoken to some, sure some nutcases claim it is the same as wrestling, but wrestling is not a betting sport with billions on the line
They are not outright fixing games either and they are not criminally liable
They are protected by their charter, plain and simple they can't be held liable or for breaking a law.
