Maybe they don't want to sell it to apple because, assuming Apple hasn't already fixed it and it is found in further generation phones, they could sell this exploit once to Apple or to quite a few big companies, governments and other entities. Please keep in mind that we still don't know how they did that. They could have just dumped the flash memory And flashed it again if 10 passcodes failed (my guess), or they might have exploited a software bug.
