That's different from what parent is saying. Parent is saying that the vast majority of viral infections do not lead to permanent DNA changes (especially hereditary ones through the germline). However, over the course of history that tiny minority of cases has accumulated to form a sizable chunk of the human genome. The quoted sentence from the article implies on the other hand that every viral infection leads to permanent DNA changes. I haven't done enough research to have a personal opinion one way or the other, but you're not addressing the point of the comment you're replying to (unless you meant your comment to be more of a tangential commentary? That despite the error in the quoted part of the article the overall point of the article still holds?).
