^^^ This.
Sorry to be blunt, but the OP has not understood the rules of the game and then cried foul. In a selfish and self-righteous quest to assert rights he didn't have, he's completely overlooked the position of the organiser and the other photographers that had gone through the proper channels in advance and paid for rights to cover the event commercially. In that situation, the organiser had no option but to decline the request, and if any other camera-toting spectators had asked the same question, they'd have got the same answer. The organiser was, in fact, protecting the rights of legitimate photographers.
