Did you actually read the post? The author describes exactly why. It's not to filter and dismiss, but it's to deprioritize spending cycles debugging and/or coaching a contributor on code they don't actually understand anyway. If you can articulate how you used AI, demonstrate that you understand the problem and your proposed solution (even if AI helped get you there), then I'm sure the maintainers will be happy to work with you to get a PR merged.

>I try to assist inexperienced contributors and coach them to the finish line, because getting a PR accepted is an achievement to be proud of. But if it's just an AI on the other side, I don't need to put in this effort, and it's rude to trick me into doing so.
