If you can't see what's wrong with that, then that's fine. It's just a base, gut reaction for me. Anything illegitimate should have nothing to do with any competitions, unless specifically allowed. That holds true for almost every other game, every other competition besides Pokemon. Maybe because it's been normalized for Pokemon players, especially now that PKhex has been a thing for multiple generations. That shit don't fly with other games though.
Who is talking about other games though? It sounds like you lost this argument and just backtracking to something irrelevant. The only thing that kind of bugs me with genned pokemon in battle is the bank ball thing and illegal combos. Well, more like I don't understand what's so appealing about say a Love Ball Chimchar. Superficial in the end. Really those get the attention of officials, I think there was a situation where some big shot US nationals player got knicked because he had a bank ball Aegislash.
As a genner, there's the freedom of not spending that much time making competitive pokemon, at the same time there are known limits that essentially balance the power to where you can't get away with a Sturdy Shedinja. If competitive battle reaches that, where someone sneaks that by (which they can't given the checks and forceful disconnects), then this issue is important to discuss, very serious matter. Really it's just trivial though, if someone wants transparency, fine, I'll admit the pokemon are genned, if I beat the person, he'll cry about that aspect rather than misclicks, bad luck, or poor decisions on his end, or just that I was the better player through strategy (and luck), being able to gen doesn't magically make me a better battler. So since the practice doesn't reach that level, why is this such a debate? It's simple, genned, legit, terms and definitions, yes, but it's still a level playing field when it comes to the actual battle.
Plus genning isn't pleasant when taking on multiple requests in succession. The last 24 hours I've done well over 100 GTS requests, meaning over 100 pokemon genned. A lot of them were Dittos, but still. That deprived me of sleep. It's off topic, sure, but you know, not all a breeze. Also worth noting that the legit user and the genner still have pre-match planning, how they obtain their pokemon has no bearing on that, I know some that take a whole week to build a team just for one match, and then they come to me to gen. The league in question lives on genned pokemon, but in the past, and I think coming up, there will be at least one person trying to go somewhat legit, he asked me today for a 6IV Ditto with Pokerus, but still. And I never seen him complain about the genning vs. legit thing. Sure everyone admits to getting their stuff genned, but still, and he's one of the better players too, so the argument about being better because of genned stuff does not hold much water.
In the end, this is just some circle, going around and around, when I got the notification that this thread was still going on with this debate, I thought "Here we go again." Pokemon shouldn't be some haven for political style battles that just keep happening and happening. They're fucking video games, chill out and just play.
