No, to "threaten" anyone in a professional context is a noob move, it doesn't work. You (or your boss if you're not a manager) just say something to the effect of: "on this team, if you don't like something, you don't just criticize, you go ahead and fix it". Basically, make empty bitching, moaning, and derision, socially unacceptable, and cultivate the sense of ownership. If nobody owns problems, they don't get fixed.
