I think he's right. A sale to Nvidia would be detrimental to ARM's current business model - now Nvidia may have other plans but the thought of that would certainly scare existing licensees even more. Should the UK government intervene? Yes. Will they? Probably not. The detail here is more nuanced than protectionist vs free market - but I don't think most people realise that and see it as just protectionism. It isn't…
There is no evidence the UK government could run ARM better than NVidia. In fact the opposite is true.
