> anything inside the UK is subject to UK law and no other law
This is true in theory but not in practice. If you’ve been sanctioned by the US then you won’t by able to get a bank account in the UK. Even if you’ve not violated any UK law.
The Americans can give a British bank an ultimatum between dealing in US dollars and dealing with a particular individual. Every bank will always choose the former.
Similarly anything with US assets is subject to the US court system any its interpretation of copyright. Naturally this means US companies need to obey its rules.
But also given the reach of copyright law, so do foreign companies that interact with US ones. Visa, Mastercard, Google, FedEx, and Stripe can’t do business with someone who openly violates US copyright.
So perhaps a local council using self hosted services could use nationalised data but that’s about it.
You’re overthinking the issue. The laws not authored but enforced in the U.K. are done so with the express authority of Parliament. Treaty ratification is literally “passing an Act of Parliament that implements the treaty in U.K. law.” Parliament can also delegate legislation authority to other bodies. It can also revoke that authority (within the U.K.) either in part or in full.
This has actually happened on multiple occasions: Brexit being one that removed European institutions’ right to set rules that the U.K. must comply with. It’s also an example of where this isn’t free: the government agreed to a bunch of rules right back because cutting ourselves off from Europe would have obliterated the economy.
