Aside from the fact that this helps Qualcomm's case in the dispute, but I glad I see some realistic thoughts on this dispute. Let’s not kid ourselves, If Apple had any chance of acquiring cheaper modems with a close enough quality to Qualcomm's, they would have thought twice. They would have abandoned Qualcomm as a supplier and that would be the end of the relationship. They bought Qualcomm's modems because they had nothing even close in terms of efficiency and quality and they paid the price for that. Nothing disputable about that if you ask me.
