This. It's the uneven application of rules from race to race that means the playing field is never level. Just like in football where a referee can exercise discretion in sanctioning a player, the rigid application of rules has shorn the competition of one of the main GC contenders (or at least made his task next to impossible) and so affects the race as a spectacle, which affects it as a commercial product. Intelligence should have been used rather than blind adherence to the law. If the commissares didn't see the incident and the TV pictures didn't show it, and Porte gained no advantage from it surely a lesser punishment would have sufficed.
