That edits the swipe of "spreading misinformation", which whilst accurate is charged and puts the reader on the defensive, as well as the more egregious "you know what you are talking about" which is nakedly aggressive. HN discussion is highly sensitive to nuances of tone, a point dang makes frequently:

(I make a point of confirming information I provide in comments, largely through inline links or footnotes. Of which I am ... inordinately ... fond: <https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...>. I've more than once changed my comment significantly on discovering my initial beliefs were false.)
