Holding back? She names her employer and her boss yet doesn’t give anything concrete, but feels okay to call him an “idiot” in the title?

She never actually outright called her boss an idiot. The most literal interpretation of the title is "if you feel this way about your boss, then here is why you may feel that way." I certainly hope that was her intended meaning, because the counterfactual is very risque. I did think the title was unnecessary though, and the naming.
