I'll skip some of those paragraphs, since I don't want to further this discussion in any direction that prompts more opinions on the result of AI usage, seeing as you're "the type of person" who's intent on prejudicially discriminating against usage of a tool in general, the people behind it, and declares their opinion the standard. I have disagreed with any statements of those kinds you made so far, and this didn't change yet, so let's leave it at that. No need to repeat ourselves.
However, I'll address a few other statements.
Using AI does not inherently train it. Some regions have consumer protection laws which prohibit that (e.g. the EU). But I'm sure you accurately decided the place of origin of this creator on your own.
And an incredibly far-fetched example of a product having been advertised as having more effort put into it than turned out to be true: any game advertised as non-AI, containing AI... wildly off-topic, I know.
"I don't want stuff made faster" You don't. I do, because it means quality stuff is made faster and more affordable, too. For you, there's still the slow-made stuff, since you prefer that. On the note of subjectivity, "your standards" doesn't preclude "basic English" — this platform still does not require projects to uphold your standards, i.e., "done properly", whereby "properly" is subjective, since it's circularly based solely on your, you guessed it (or not), standards.
Why do you want to take something away from people who have a different opinion? And why do you generalize everything? "Any usage of AI always results in trash, and anybody who uses it doesn't know how to program," to summarize a bit. And, most importantly, do you actually practice what you preach here? You do realize that many modern games used AI in some form to accelerate development, right? Not just triple-A, most of whom cause harm by laying off their work-force in favor of AI, but also a vast plethora of Indie titles did, too, who simply increased their production speed or quality, or lowered the investment risk.
Also, on a side note, when you want to create something, you win once it's been created. If they used AI for that, that's apparently fine with them, so why would it not be a win for them? If they ever decide that's not up to their standards, they'll certainly improve upon or redo it, if they have the time, or remove it, if they find it unpleasant enough.
And I cannot agree that the website has "gone" to complete shit; it looks the same as ever, to me. How one classifies that is another matter. You have to scroll past AI stuff? Well, that's because you don't like it. I absolutely cannot stand a specific genre that floods the lists here, but never has it crossed my mind to complain about people publishing works of it's kind, as low-effort compared to other genres as I regard their production to be, which it is and which is why it's so common.
"It's both" You believe people use AI *because* it produces low quality? That's a hot take right there...
"I can also criticise it." "One can do anything that may become a man; who will do more is none", to paraphrase some random guy. I.e., you can, but it's improper.
I doubt I'll agree with telling anyone not to use something for a personal project, as long as it doesn't harm others, so that's it from me trying to convince you to let them use the tools they like. Should itch introduce a no-AI policy and anyone infringes, even slightly, I'd be fully with you. But that isn't the case; it's not some unfair advantage, it's not defrauding anyone, it's not hindering others, it's nothing. Or is it any of those, or something I missed, to you or anyone else?
