A wide coalition must form: every single OEM acquiring ARM will reduce its value. BTW Apple won’t let Nvidia control a central part of its Long term hardware strategy.
I don't know the details of Apple's licensing agreements, but note the fact that the word "ARM" is totally absent from all their marketing. They own their own chip design company (PA Semi), we know they're using the ARM ISA, but I suspect they don't need anything from ARM the company anymore.
