How is SoftBank selling ARM? (And how did Google acquire Motorola and then sell them off to Lenovo, for instance?) Is there a difference between how they acquired ARM and how Nvidia wants to acquire ARM that makes it a merger instead of an acquisition or something? I honestly don't know and am curious and think there's an interesting point here if how I'm interpreting your comment is correct.
