After reading this piece, where the President of PayPal vents about HQ staff refusing to utilize the company's product and tools, I get David Marcus' point. There is a danger, though, with the confrontational leadership statement. Sounding whiny and entitled trends to disconnect you further from your audience, in this case, your employees. Scolding tones need to be used with caution and thoughtfulness. Undermining your connection or weakening team trust is hard to repair.
Ultimately, it's really hard to gauge the effectiveness of one communication without seeing the larger context. Arm-chair quarterbacking is easier that doing the work.
