I take it they found the advice incomprehensible, not the article itself. Like when someone says "always use the right tool for the job" but consistently fails to say what tool is right for what job and what makes it so. It's hedging so severe that you may as well say "I have no opinion."

Nice explanation. I would add “I have no opinion but I still want to look like a leader”. It’s the same with guys who always ask “insightful” questions but never answer a question.
