Sucker got unsuckered ?
re "it would be allowed sell off the Mesa facility and return the money to Cupertino, without disclosing any further information about the companies' relationship."
So it goes like this? :-
GT did the donkey work but Apple had a better deal planned with a more skilled tenant once GT sapphire kit was in. And GT extracted something for themselves via semi-blackmail.
Apple still suckered them good and proper.
