No, I think parts of this are very true. Apple Retail doesn't pay their staff commissions so there's no incentive to drive expensive sales that the staff personally profit from (partly I guess because of just how expensive and seasonal Apple product sales are?).

Myself, and a few other developers, refuse to monetise our third-party apps for the video game Destiny because doing it for free means we have no obligation to any customers. If I was being paid to do this, I would enjoy it a lot less.
