I don't think it's rude, it saves me from having to come up with my own prompt and wade through the back and forth to get useful insight from the LLMs, also saves me from spending my tokens.

Also, I quite love it when people clearly demarcate which part of their content came from an LLM, and specifies which model.

The little citation carries a huge amount of useful information.

The folks who don't like AI should like it too, as they can easily filter the content.
