It's not just the British, it's all "core western" nations honestly. USA most of all, it is of course funny that a British regulator tries to do that with an American company, that doesn't happen often.
They demand fulfillment of their laws regardless of jurisdiction when the other side is weaker, and ignore laws of others even if firmly inside those others' jurisdiction. And that's so normalized that nobody even thinks about it except for such funny moments.
There are honestly worse things.
All of Mediterranean border and migration matters are resolved in this way, there are "coast guard" military organizations on the African shores with their own small concentration camps for those attempting to illegally migrate to Europe (not nice, of course, but doesn't warrant such conditions) which in reality are funded by Italian and French governments and really report to them and act in their interest. I think I've read a few articles describing those.
It's not been so long since France enforced its laws on much of the African continent. Due to malicious and incompetent jerks in its top, it has lost much of that. And I hope it'll lose everything colonial, French Guyana included.
I've read just yesterday about British troops and Kenya in the context of a murder, which was pretty known in that regiment, with all the circumstance, and the perpetrator is a vet living in UK just fine with family and all, and more than 10 years after the British have formally started some kind of investigation, and it will apparently go on for a couple more decades. It's literal mockery of the victim's family, and it's normal for Europeans in such cases.
Hell, even western policy on Armenia is not a result of some rules, it's a result of one European politician with connections having their ass torn by bandits in Armenia in 2012. They are taking revenge for that. They think thousands of honorable decent men dead are worth less than one criminal's torn ass. That a whole nation with its history is worth less than that. That they have right to think and act like that.
If you want Europeans (and Americans, and Australians, and Canadians, and so on) to learn honor, you need to have that whole imperial bunch thoroughly defeated by Chinese, or by India, or by them all together, or whatever.
Otherwise it's simply unnatural for humans to know their borders. While the empire (in the British and French, not in the Roman, nor in Chinese, nor in Japanese, nor in Russian, nor even in Spanish meaning) is still alive, it will morally decay further and further.
And you know what's the funniest? Growing up in Russia I thought I'm smarter than people around me for thinking that the general sense of what I just wrote is all propaganda. LOL. Soviet and Russian propaganda softened that reality, if anything, they had and have to somehow justify dealing with those nations. Modern Russian propaganda didn't stop that too, they are just adding some delusions on the side.
If I recall, the US vehemently disagreed with the right of the British to enforce their laws here. Quite successfully, I might add.
