Most people would interpret the claim as concisely expressing that you get better accuracy from grumpy SO users than friendly LLMs.

Read carefully and paraphrase to the generous side. The metaphor that follows that is obviously trying to give an example of what might be somehow lost.

Note that "answers your question" does not mean "solving your problem". Sometimes the answer to a question is "this is infeasible because XYZ" and that's good feedback to get to help you re-evaluate a problem. Many LLMs still struggle with this and would rather give a wrong answer than a negative one.

That said, the "why don't you use X" response is practically a stereotype for a reason. So it's certainly not always useful feedback. If people could introspect and think "can 'because my job doesn't allow me to install Z' be a valid response to this", we'd be in a true Utopia.
