If you want the story to play out differently, more evidence needs to come out.
So far, we can only talk about ethics, or talk about the legality of playing doctor, but there is not much that show that a WADA defined doping violation has ever been committed by Salazar or Rupp. It's possible that he only broke some laws, but not any WADA rule.
It's not about Nike or Salazar controlling the message -- there is simply too little evidence to talk about doping/cheating with banned substances or methods. The only possible thing that can happen now is that WADA look for ways to minimize TUE abuse, and look at some permitted substances more closely, so that the only permitted usage is the intended medical doses.
