The simple answer is to not recognize the authority of the UK government when you don't have a physical presence there, as long as they are failing to protect their citizens with sane, ethical digital policy.
Tough pill to swallow for some, but there is no difference between irrational demands made from the government of the UK, and say, North Korea. It's everyone's choice which side of history they'd like to be on.
