I dont know if anybody mentioned this, but Bobby B snapped his pole after being incredibly nice to his fellow competitors. He said he was happy for the other guys, thought they killed it, but was bummed that he couldnt defend his title. He had a smile on his face, and made it more about the other guys' success than his failure.
Anybody would be angry, and surely snap a pole if they went into an event as a favorite, got injured skiing a mini park, and was unable to put down a run that he or the judges were happy with. It's his paycheck.
Sure, the exact action was the same as what Simon did, but it is what they did before and after that made the difference.
