We are fans, Most we do for this club is walk to stadium, watch the match, get enraged & post online.
Olympics happens once every 4 year.
Athletes prepare for it for entirety of those 4 years or even more.
You want them to abandon their dreams & efforts because the organiser couldn't do their job?
I would understand your point, had the condition were disclosed 4 years ago.
But these conditions are only known 2 weeks before the event.
How difficult is it to understand?
