Marissa Mayer is too Busy to Lock Her iPhone

Senior managers are the worst when it comes to security. "I'm exempted because I'm too busy/important."

I suppose you could argue it matters less above a certain level. Because the CEO is often surrounded by an entourage. And instead of the device being left behind in a taxi or airline, it's a private limo or private jet. Even so, the danger zone is when the CEO spends some time living like a normal person.
