RISC-V is open source
>It’d be nice to not hand the US control of all major processor architectures.
True and the next president of the US will certainly continue the tepid war with China. However the damage has already been done; blocking Chinese (mainland) access to ancillary technology is as effective as blocking the CPU tech itself.
Possibly the US will relax these restrictions if we control the ARM as well; then the mainland will be faced with off-shore designs that increasingly use other US designed components. US behavior has always been incredibly US-centric even before our current president.
The one sure result is that RISC-V, or a fork, will become the dominant technology. Open sourcing the ARM is the only way of avoiding that and that will not happen. The lackluster approach of forcing ARM Ltd to become a public company doesn't mean the tech can't be controlled from these lands; such control merely requires arrogance.
Or maybe someone out there thinks that the original arrangement, back when ARM Ltd was controlled by Olivetti and Apple, might work? There was some notional idea that the ARM licenses had some manner of control or input so that if Olivetti or Apple started to get scared of them neither company could lock their competitors out of the design process. I don't know how that worked but I doubt it would work today even if it worked in 1990.
Of course BoJo could nationalise the operation on the basis that it is a strategic resource that should not be controlled from elsewhere.
