I disagree that this is a clickbait title. I also disagree that those complaints are worth discussing. The guidelines specifically discourage us from complaining about things "too common to be interesting." And the articles that I'd describe as clickbait are simply too low quality to be posted anyhow. ("Clickbait", in my mind, is when the article uses provocative language to build expectations that it doesn't or can't deliver upon. "Trick" in this sense pretty clearly means, "here's a tool you can use to serve different content types to different user agents," and it delivers on that.)

These are really stylistic complaints; the author expressed themselves in a way that's not to your taste. Your tastes are valid, but there should be no expectation that every or any article will cater to them, and their not doing so isn't a criticism of the article and isn't something we can really have a productive discussion about in this medium. I find people use the term "clickbait" to try and reframe their tastes as something more objective.
