Put quite simply, for those who want exercise to be a sport, there have to be standards.
Nobody really cares about someone who can quarter-squat 2000 pounds, because most everyone doesn't consider that a competed (or completed) exercise.
If a guy false starts in a 100m race, yet ran a (later analyzed by video) 9.2 sec. 100m, while the performance is incredible, it still doesn't count for the record books. That guy isn't the new "fastest man in the world" until they do it *right*.
I'm amazed at when form is obviously sub-par (ie. not a single lockout, for example), yet everyone only wants to defend the "effort" and almost act like the effort put out (or the fact that the person--like David Morgan--is insanely strong) somehow relieves the person of having to hit movement standards. It doesn't, and it doesn't mean that the performance isn't impressive.
People who don't squat to competition depth in practice get a really rude awakening when judges actually give them red lights in competition.
"Great. You attempted to squat a PR, and you stood up with it. Sorry, it wasn't deep enough to count. Great effort, though!" It's really that simple. Same thing applies here.
