I can imagine a moderator, or a marketing person, wanting such a tool. "Respond to this post in a polite and friendly manner, thank the user for choosing our company, discovering a problem, and taking the time to report it. Promise to sort this out quickly. If the user is really angry and threatens legal action, promise an immediate refund, and shoot me an email with the summary of the issue, and all the details."

If instead of a copy-pasting spree, or setting up a whateverClaw, the user might just click a button in Chrome, it could be actually useful. (Consider a dozen such buttons.)
