It's a bit imprecisely worded, but the message isn't very controversial I would say. To get things done you can't be afraid of disagreeing with people. You can be a jerk about it or not. If you're a jerk you likely free up resources for getting things done since you're not spending energy being sensitive to other people's feelings. On the other hand, if you're a jerk, people might work against you just because they don't like you. Also, it's easier to effectively lead if you're not a jerk, which is more effective than working on your own. Most people can be adults about it, disagreeing civilly, and laughing about it afterwards. But the people who change the world are the ones who care enough to risk becoming jerks over the things they care about.
