they are corrupt for one thing. If you are interested in a really good movie that exposes them back in the '70's, it's about one of USA's all time greatest track stars and his coach who created Nike, He was at the University of Oregon where he worked with the legendary coach Bill Bowerman, later to Olympics in Munich where the governing body that it's my understanding were the ones that kept them from being paid athletes, would play games with his eligibility so that they could extract fees in put in their pockets to get him to race at non Olympic events and if he didn't and ran in the races they didn't want they would use their pull to have anyone that raced against him banned from Olympic eligibility.
If they get sued then it would likely change as that's what has happened in college football if I'm not mistaken.
