The article says they could have asked an AI themselves, but that is missing that I may have an agentic context with exactly the right information to answer the question well, which they do not have. For example because I worked on something closely related. Such an agent output is very useful, and taking the time to rewrite that to a short personal answer is not always worth it.
Your agentic context is still going to shit out 3 pages where a sentence would suffice. Use AI all you want, and then WRITE THE ANSWER IN YOUR OWN WORDS.
In that case why not just say you'd prefer not to answer and move on? They're asking for your input, not AI input - if you'd prefer not to contribute literally just say so.
