Because sometimes the reason is wrong, or misunderstood. And if you go through life accepting something the way that it is just because it is that way then you're not very likely to succeed at much.
There have been many examples within this game alone in which reasons we were previously given had circumstances change, and priorities managed differently. Closed domes, re-coloring of uniforms or additional uniform slots for some teams, style guide limitations, and named brands on equipment, were just a few things that got fixed or put into this game in the past 2 iterations because of things brought up or demanded by this fan base alone.
So to scoff at people who push for answers, especially in a polite and productive manner, just because something isn't personally important to you or your enjoyment of the game is pretty unfair to those that do care or wonder at the very least why things are the way they are.
And if nothing else, even if things cannot be changed, it hurts no one to get clarification on these matters. And would also save everyone here a lot of time in explaining to every other person that comes in with these same questions. Like they always say, you'll never know unless you ask.
