If you look ar ARM cpu's as bits of lego, sure you can use this brick or that brick to make your CPU, but it's still made out of standard bricks. Given that it may be understandable for Keller to move onto something more of a challange for a person who likes to design the bricks. Apple don't need to make there own add on's, they pick what they want and what they don't want/need and in that the level of skills needed to assemble those parts onto a workable CPU is at a level were you don't leverage the skill set that Keller has as much as you could. I can understand Apples needs and what they don't need and in that it is non impacting to Apple and probably a good move for Keller. To read anything else into this story is clutching at the speculation stick and has no grounding.
