From <https://arstechnica.com/gadgets/2021/02/nvidia-wants-to-buy-cpu-designer-arm-qualcomm-is-not-happy-about-it/>: Owning Arm outright would also allow Nvidia much greater leeway to innovate upon the design. We've spoken to several vendors who described the sort of innovation that the RISC-V architecture allows as effectively impossible with Arm; the vendors have said "they just won't let you" make changes, like adjustments to the instruction set. If Nvidia owns Arm, it will no longer face such restrictions. And it will be the only company in such a position with respect to ARM. That may make it more competitive with RISC-V, but it will likely just drive other vendors away from ARM ... and towards RISC-V.
