The more interesting question to me is what would any single (major customer of Arm) company gain from owning Arm? For instance, if NVIDIA wants to be competitive in data center CPUs (which would put them at equal footing with AMD and Intel, not more monopolistic), why couldn’t they go the Apple approach with a perpetual license and design it entirely custom (or not) as they see fit? (AFAIK they already design custom mobile CPUs.)
What do you gain by buying out an expensive, large licensing company that essentially makes no money that leaves you in a weird position with various rivals? Doesn’t quite click for me.
