I've been trying to mull that out as well from an economic perspective but I think it's highly dependent on the existing distribution networks which adds additional complexity. Major League sports information is disseminated fairly quickly and the attendance levels make technological prohibitions a challenge. The nature of world chess championships make it a little different, as long as the globally recognized top ranked players are in attendance (preventing an organizational schism) I think the organizers could do whatever they want. In the end I think this ruling just means they can't enforce a civil penalty for violation of these rules, but there's no reason they can't expel the violator from their event. It's an interesting case.
