Why would you read the press release at all? Do you expect a company to not do what's in their own financial self-interest? Look, I love nVidia. I only buy nVidia GPUs and I adore their devices like the SHIELD TV, handheld, tablet, even the Tegra Note 7. Even I can see that they're not just buying ARM on a whim. They intend to make that money back. Them using ARM to make that money is good for absolutely nobody except nVidia themselves.
I'll listen to what they're saying but I'm paying far more attention when I look at what they're doing. The only way buying ARM helps nVidia is by damaging their competitors, AKA almost everyone.
