Seriously, abusing a mechanic that is hidden deep within the game is low. Learn how to play the game properly.
The Regis were hidden deep within R/S/E, so having them must be low as well, as well as any other secretive legendaries. If I find an hidden item, I shouldn't use it either? I should learn how to play the game properly and ignore anything that is hidden.
EVs were put into the game deliberately, and the designers admit to having put them in to support the metagame. You get in-game items and services entirely designed around manipulating them, and while there aren't any specifics, a few NPCs give vague hints about them.
RNG abuse was unavoidably left in the game for the sheer fact that it's a video game on a miniature computer (video game consoles are basically specialized computers), and computers can't do true randomness, so they fake it as best they can. It's certainly not what the game designers intended at all, and they went out of their way to obfuscate it, dropping not a single hint on how to manipulate the RNG at all. I get the feeling that if the game designers could easily use a truly random system, they would... but they can't.
Not exactly the same thing.

But it's not hidden, you can literally buy EV points
Can you find the maximum amount of EV points per stat in the game normally? No.
Sorry but out all of the reasoning you could have made - this is your argument?
You can find out by phoning Bianca - she tells you everything!
And in every game, in every RPG, there's a way to determine stats! It's up to the player or not whether to find out how exactly they are implemented. We're not cheating. We do it in the confines of the game in front of us. However, hackers use an external device and are clearly not doing what the developers wanted the players to do. That's cheating. It's cheating because it's a shortcut/doing something that normally would be very unlikely/impossible.
