How do you "pull out" of the UK if you are not a UK company, you are a US company, hosted in the US, and proxied by Fastly. There's nothing to do? You do not need to abide by UK laws, even if your website is accessible from there.

The US does exert its laws extraterritorially when there is a sufficient nexus to US interests too. Why wouldn't the UK be allowed to do so?
