But that's the deal with sports. There have to be rules, and there has to be a bright line, and nearly always the location of that bright line is arbitrary. That's maybe seen most clearly and most heartbreakingly in the case of intersex athletes like Dutee Chand or Caster Semenya, trying to compete under gender-binary sporting rules. Why is a regulation baseball a certain size, why is a football field a certain length, why is there a limit on how far forward you can set your seatpost, why do MotoGP teams have to seal their engines at the beginning of the season, why are some drugs banned and others are not? It's all arbitrary, and that's what makes it sport. Part of the job of an athlete or team is to do whatever they can to improve their performance without crossing that line. Part of their job is to get as close to the line as they can. People who get caught on the wrong side of the line deserve to be sanctioned, and people who stopped short of it deserve to be rewarded, because it's sport. It's not like it's, I don't know, being a teacher, or bidding for a highway contract, where you can legitimately say the spirit of the rules should be honored. In professional sport, rules have no spirit - they're just arbitrary lines by which the game is created.
