These are three distinct races. No one has to enter all three. Winning all three is difficult, like winning a grand slam. It takes different abilities and skills and some chance (weather, competition) to win any one race, let alone these three. Whining about your opponents is poor sportsmanship. The dude believed the media.
When I re-thunked it I realized you are right. Even if the rules were the way Chrome’s owner wanted them, there would still have to be an asterisk by Chrome’s name, since all the other Triple Crown winners had won by the established rules.
The owner expected a coronation, not a race.
