> "The UK government can certainly insist that a company not based in the UK carry out its orders – that situation is specifically included in the new law – but as to whether it can realistically impose such a requirement, well, that will come down to how far those companies are willing to push back and how much they are willing to walk away from the UK market."
But I cannot see why someone would comply with that. For example getting an AWS machine in Ireland, is that within the "UK market"? Does amazon have to comply just because many customers are in the UK? And will we ever know if they do comply? What a mess.
I'm absolutely sure by now someone has written a program to automate this, and to be honest I expect some governments already force some companies to do this.
