Ever since LLMS became popular, there's been an epidemic of people pasting ChatGPT output onto forums (or in your case, offering to). These posts are always received similarly to yours, so I'm skeptical that you're genuinely surprised by the reaction.

Everyone has access to ChatGPT. If we wanted its "opinion" we could ask it ourselves. Your offer is akin to "Hey everyone, want me to Google this and paste the results page here?". You would never offer to do that. Ask yourself why.

These posts are low-effort and add nothing to the conversation, yet the people who write them seem to expect everyone to be impressed by their contribution. If you can't understand why people find this irritating, I'm not sure what to tell you.
