Bull.
I've been in the semiconductor industry all my adult life and I've seen this type of play before. Apple, or someone else, is making the unreasonable demand that they want to know the cost of Qualcomm's chips so they can determine (cough, cough) if they are being paid a fair price. This is, of course, bullshit. I've had this demand made of me before and I politely tell them "no".
The price of something is the market value that people are willing to pay for it. I learned this in high school. If you have something nobody else has, you can charge a premium for it. Duh.
Also, you don't license your most competitive IP to your competitors because they get to see your proprietary IP and put you out of business.
Last, I doubt Apple is being given a "rebate". Apple is being given a standard volume discount, but since Apple buys in such huge quantities the discount may not be figured out until later.
It looks like somebody in the FTC has been paid off, big-time.
