I was reading this article the other day, which is a story about how the CEO of PayPal recently condemned his staff in a company-wide email for not using the Paypal app on their own mobile devices. My first reaction was 'surely you can't condemn staff who don't like your app?' Isn't it worse for them to pretend to find the PayPal app useful and only download the app to keep their boss happy? But this guy is the CEO of a successful tech startup (many reports I have read suggest that David Marcus has single-handedly re-invigorated PayPal since he joined), so admittedly I am in no position to question what makes his business work. David must have had his reasons to send this email.
