That doesn’t make any sense. It’s not wikimedia’s responsibility to ensure people from the UK don’t hit their servers by typing wikipedia.org into the browser bar.
That does make sense, but then that would mean that any business not doing business in UK would not have to follow the rule, which would make the rule worthless. But I hope I am wrong.
"It doesn’t matter where you or your business is based. The new rules will apply to you (or your business) if the service you provide has a significant number of users in the UK, or if the UK is a target market."
I’m sure that they can write that. But their actual enforcement mechanism is nonexistent. No country is going to work with the UK to arrest someone that does that when the same thing isn’t illegal under their own law.
