Just a reminder GT did not sign on the dotted line, GT is not a real person not matter how many deceitful and disingenuous corporate types like to pretend it is, in order to shift responsibility away from themselves to other people and make them pay. So why would the corporate executives of GT sign, what kind of motivation would they individually need to risk their whole company in order to provide Apple the best deal possible. So how much money and risk could Apple save by investing in the executive team of GT, keeping in mind as per typical executive teams the one thing they always put in place for themselves is a golden parachute when it all fails. So how much would Apple have to shift from one offshore tax haven bank account to another offshore bank account to basically get corporate executives to stab their own company in the back, keeping in mind Apple could save hundreds of millions of dollars over the life of the contract or eliminate hundreds of millions of dollars of risk.
Strange things go on in the world of finance where investment companies routinely buy into doomed companies, that enable vulture capitalists like Mittens Romney to make huge profits. For some strange reasons those executive teams of say pension funds go stupid and buy all sorts of crap for billions of dollars and yet they all still retire rich no matter how much other people's money they lose.
It should be pretty obvious by now when it comes to corporations, psychopathic corporate executives always act in their own interest and whether or not that serves the interests of the company they work for is completely arbitrary.
This is a case of over eager executives at GT biting off more than they could chew and a bunch of over eager executives at Apple trying way too hard to maximise profits with the result that everybody ended up with egg on their face. So IMHO they are both to blame. GT had the option of not signing a deal that was "onerous and massively one-sided" and telling Apple to go jump in a lake. As regards Apple they should have known better than to offer GT that crappy deal in the first place. I mean saving costs by not to installing backup power supplies on the sapphire growth furnaces, really? Contrary to what some people in the business community seem think you CAN actually end up paying a dollar for trying to save a cent. Somebody at Apple got too greedy and they deserve being a laughing stock of the tech industry as a result.
