As someone familiar with Hardrock, my thoughts follow.
First, Hardrock is a game contrived by the event organizers. The course itself does not follow the logical easiest route. For example, instead of taking the rough steep existing route down to a known point, they send you up, over, through willows, hills, rocks, swampy areas to get there. Part of the game seems to be a desire to make completing/finishing the game as difficult as possible. The easy options have been eliminated.
They likely call it a run not a race because the terrain, weather, elevation, etc. can be severe enough to be life threatening. Their guidebook states that the cutoff time to complete the game is long to allow participants to hunker down in safe areas to avoid severe weather and lightening. I believe they would prefer people choose safer options rather than risk their lives. This only works with fitter/faster runners, and the reality is there are many people who now enter the game that are not fast enough to take time out during the run to complete it within the cutoff. Race implies risking all, a run is more calculated.
Hardrock does not adhere to normal track and field/athletics/running rules. The IAAF competition rulebook is over 230 pages long. The 2018 Hardrock Runners Manual, which contains 11 Executive Rules, some other rules, but is mostly other information, is only 16 pages long.
Hardrock event organizers make up their own rules.
If you want to play their game, you have to follow their rules.
If you do not like their game, don't play it.
You can always try to start your own game.
Obviously those leading events receive greater attention and thus may be under higher scrutiny than those back in the pack.
Leaders must accept this fact, and understand that their actions are being watched and what they do may have consequences.
The question is will the Hardrock game directors try to enforce their own rules consistently and evenly for all players in the future?
Probably not, because their existing rules are not clear (are they "Executive Rules" or "guidelines") and the consequences for violation of these are also not clear.
