I simply choose to believe that people do this out of a place of genuine curiosity / excitement to share knowledge. I believe this approach of assuming the best of intentions is even in the HN guidelines! Or maybe it was just the old Reddit ones from long long ago when Reddit was more like what HN is now. Either way, maintaining the background assumption, even when it is challenging to do so, makes HN a far more pleasant place to inhabit.
