Right, and everyone's subjective definition of what is outside of bounds is different, a lot of people happen to believe whether the bug or exploit is within the code or put into the code by an outside device it's still cheating. The only way to make a fair comparison is if everyone plays by the same rules. If everyone is off doing their own thing because "in my opinion its not cheating" then there's no competition because everyone is playing some different modified new version in their own world. There's no half measure.
What we have here is a guy who designed his own game around tasks contained in the cart, got popular because the game was OoT, and got very very skilled at some weird player hack of a game with new rules. The article is leading with a foot that's implying this is somehow a feat connected with OoT, equating a 20 hour normal clear with flawed code that created an entirely separate game.
As someone who grew up in 8 and 16 bit eras, these types of articles are misleading fresh blood into believing taking advantage of glitched code is skill at the game. It's disrespectful to those who put effort into creating the extraordinary mechanics in some of these games that were meant to be used and not exploited. It's almost a form of plagiarism.
It is much easier to beat OoT in 20 hours, than it is 18 minutes.
