You're probably a really good writer, and when you are a good writer, people want to hear your authentic voice. When an author uses AI, even "just a little to clean things up" it taints the whole piece. It's like they farted in the room. Everyone can smell it and everyone knows they did it. When I'm half way through an article and I smell it, I kind of just give up in disgust. If I wanted to hear what an LLM thought about a topic, I'd just ask an LLM--they are very accessible now. We go to HN and read blogs and articles because we want to hear what a human thinks about it.
People talk about using it because they don't think their English is good enough, and then it turns out their English is fine and they just weren't confident in it. People talk about using it to make their writing "better", and their original made their point better and more concisely. And their original tends to be more memorable, as well, perhaps because it isn't homogenized.
