I'd argue the opposite; you remember the minority of cheats because they are so blatant and against the norm within sport. I'm not too sure what sport you watch, but...
...you're a sportsman, it would appear; do you consider there to be a difference between gamesmanship and cheating?
If no rule is broken, no accepted standard (such as TUE) is abused, then why do you believe highly capable, professional medics and managers succumb to brain farts when recording their must-be-recorded activities?
TUEs are there to support the inclusive aims in sport for those with certain health issues. Do you believe their use should be banned and put over there on the shelf, next to the jiffy bags containing integrity and rocking horse ****?
