This policy, and most of the comments on here, miss the point entirely.
Open source is supposed to be primarily a labor of love, scratching your own itch, done for pride and a sense of accomplishment of having done it right.
Using an AI chatbot achieves none of that. It's an admission that you don't have the skills, and you're not wanting to learn them. Using AI to contribute to an open source project makes NO sense whatsoever. It's an admission of incompetence, which should be profoundly embarrassing to you.
I realize I'm screaming into the void here on HN, where so many people have bought into the "AI is just a tool" bullshit. But I know I'm not alone, even here. And I know that e.g. Linus Torvalds sees right through the bullshit as well.
