I can definitely see that argument, but I feel the issue is that Ive lacked a product-focussed and customer-focussed CEO to reign in his "wilder" impulses (the Edition watches are another example of that).
Jobs may have managed Ive's drive in a way that would not have seemed bean-countery to him but customer-focussed.
In other words, Ive was only a liability in so far as he had no actual peers at the company to reign him in. And it's debatable that that's not really his fault.
