I don't think UK politicians are even appreciating it let along acting. Still pushing for US AI software in US owned data centres on US hardware with the "Kill Switch" in the US but located in and polluting the UK - all so our politicians can clear their FOMO.
And still Government embraces Palantir (with their far-right chairman) - more critical systems owned by US, "Kill Switch" held by US (specifically US Techbros disagreeing with UK democratic governments). Not long since Sadiq Khan sensibly blocked the MET from adopting Palantir (so US would have the "Off switch" for some Met Policing systems. What if Thiel decides the UK should operate an insurance based health service ('cos some of his mates run health insurance companies) and suddenly the NHS loses it's FDP IT platform (like Ukraine lost Starshield on some whim of some US individual who wants them to lose a war to Russia).
etc.
