It's funny because few things make me seethe like someone talking to me in this way during a high stress moment. The artifice is transparent and if the conversation is tense the tone is quite easy to read as condescension. I'm hardly dismissing NVC as a tactic, just that when done poorly it's worse than simply being direct.
I supported my girlfriend throughout her grad studies to become a therapist. A huge part of her studies were in NVC. Even though I didn't go to school with her, I spent a lot of time with her classmates. Nearly everyone's conclusion, after 3 years of being deeply embedded in NVC, was that they hated it. And for the same reasons you describe.
Yes, there are better options, but most people are manually copy/pasting files into backup folders before making big changes.
