I think there is meaning to the use of that word. It's not just an ad-hominem snipe, but it's an accusation on the values of these individuals' motivations.

When somebody says a CEO is a sociopath they are essentially arguing that the CEO has little/no empathy, believes their success is due to their own inherent superiority, views morality/law as an obstacles to their success, and defines success as in personal achievement without regard for collective wellbeing.

Moreover, by name-calling the trait (using a derogatory word) one is collectively reshaping the cultural definition of success away from "Make billions of dollars you have no need for and are going to leave to your kids" toward "Make the world a better place."

So I disagree on every level I guess.
