> I'm still unclear why Nvidia would want to control Arm.
Nvidia have some really good high performance Arm cores that they've developed and sold (Denver, Carmel). Continuing to invest in that area makes some sense for Nvidia today, but it would make a lot of sense if the products they're paying to develop were official Arm products sold through the Arm IP sales channel. In other words, it would increase Nvidia's return on investment on work they're already doing.
(on the other hand, the amount they would have ended up paying for Arm might be fully justified by the value of the company but it was really, really high)
