The stronger argument I think is that Apple did not get its App Store put into a global standard which can't be avoided in exchange for promising to let people sells apps on it under FRAND terms.
Apple can do whatever it wants on its own App Store. It's their device and they aren't a monopoly nor is it anti-competitive for them to charge a high fee on their own store.
But Qualcomm IP is part of the LTE standard on the express condition that they will license their share of LTE mandatory features fairly. I don't think it's fair to take a percentage cut of the whole package price for an IP license that's part of a global standard.
