Emotion is great. I want to understand other people's emotions, which means titles should express them if they are present. It's for precisely that reason that I appreciate tamping down "over the top" linkbait, if that's what this is.
Understanding others' emotions gets hard if everything is a life-threatening emergency†. It's like watching CNN during their worst years: every possible event got a "BREAKING NEWS" banner. It made it hard to stratify emergencies. If every title devolves into "THE INTERNET IS ABOUT TO EXPLODE because git just went to v2.8" HN would become useless to read.
† I'm not saying that's what this article is doing, just making an example.
