I love when <works ridiculous hours> is presented as some kind of flex. It isn’t. It is a reliable indicator of chronic mismanagement, not only of their own time, but of the time and capability of everyone else around them. Guaranteed these folks didn’t get their job on actual merits - possible perceived merits, sure, but again guaranteed that scratching the surface will reveal all kinds of nasty.
In this case - the App store is a case in point. It is a financial success despite, not because of its’ management, and the many myriad of ills that beset the App store (and have been for a very long time) clearly show this to be the case.
