They're inferring based on two sums that actually aren't "very close." (If I offered your choice between $60 million and $75 million, are you going to say, "It doesn't matter, the numbers are so close." They're not; the latter is 25% more than the former.) As evidence, it doesn't get much flimsier.
But I must say, I really Iike the idea of CEOs taking personal and financial responsibility for the screw-ups of their company, instead of the usual finger-pointing, buck-passing and scapegoating.
Maybe even just the rumor of Cook -- who, after all, is chief executive of the most successful technology firm in the world -- paying out of his own hide to cover the cost of Apple's blunder will embolden other CEOs to step up and be accountable, no matter what the consequences to their net worth! To show what kind of responsible and selfless leaders they really are!
Sure, like that's going to happen.
