Hold up. Apple are the reason GT are in this mess.
Apple: "we will loan you $500m for new equipment to make sapphire for out phones"
GT: "ok"
Apple: "you can't sell the sapphire to anyone else, only us"
GT: "ok, we will give you exclusive access because of the loan."
Apple: "we don't want your sapphire now, and you aren't allowed to sell it to anyone else."
GT: "WTF! How are we supposed to make money?"
I noticed how you conveniently left out the part where GT didn't live up to their end of the deal: "GT has not yet received the payment because it has reportedly failed to deliver on the technical milestones that it was contractually obligated to meet under the original terms of the $578 million loan that Apple provided for purchasing equipment."
Think about it. Would you pay someone if they failed to fulfill their obligations?
