They do in most cases today. You do realize that ARM was started as a joint venture by a few companies, including Apple, right? Some of you kids need to do your homework. As for the rest of your comment (the part I didn't quote), I don't understand what you're going on about. I was saying that Apple didn't have the capability to build their own GPUs from scratch, so it would make sense to pick up talent and designs from Imagination and integrate them into their existing chip teams so that they can better streamline their entire process and more completely own the technology that makes their devices so fast and energy efficient.
