I see it equivalently helpful to the folks who paste archive.is/ph links for paywalled content. It saves me time to do something I may have wanted to do regardless, and it's easy enough to fold if someone does post a wall of response.

IMO hiding such content is the job of an extension.

When I do "here's what chatgpt has to say" it's usually because I'm pretty confident of a thing, but I have no idea what the original source was, but I'm not going to invest much time in resurrecting the original trail back to where I first learned a thing. I'm not going to spend 60 minutes to properly source a HN comment, it's just not the level of discussion I'm willing to have though many of the community seem to require an academic level of investment.
