Don’t allow a monopoly from day one and companies will understand clearly what’s expected to do business in the UK.

I mean, Apple didn’t “sneak” and create the iPhone, then “sneak” and provided an OS for it, and then “sneak” and put it on sale in shops and then “sneak” and created a programming environment for it, and then “sneak” and created an App Store and then “sneak” and allowed developers in the UK to create apps to publish on that store. The UK government saw EVERYTHING that Apple was doing and were perfectly fine with it, signing off on each thing they wanted to do. They could have said, “Nope, no iPhone in the UK, we’re sure that’s not a thing our citizens would like.” and we wouldn’t be here.
