I think that the style itself is very clear and has its advantages, it's hated only because it's from LLMs, which are not liked when used without judgement (which is often the case).

So, someone who falls on the side of not completely hating LLMs for everything (which is most people), could easily copy the style by accident.

> It's hated by everyone, why would people imitate it?

It could be involuntary. People often adopt the verbal tics of the content they read and the people they talk with.

Then why does every vibe-coded "Show HN" app have it in README.md? Surely authors would edit it out if it was true that everyone hates it.
