It’s fine. I don’t see the click-bait-ness of what the other person is talking about. Especially since I’ve run into the title length limit before. Some people have bad days and are more (overly?) critical.
“You Can't Build Interactive Web Apps Except as Single Page Applications” is false, which would make that title clickbait, specifically of the “ragebait” family.
You obviously shouldn't build interactive pure-HTML apps, but that’s a talk for another day ;)
