> But where have X violated US law? It clearly continues to confuse that EU law does not, in fact, have any relevance outside of the EU.

US law is not relevant in the EU. As long as X makes itself available in our sovereign lands, they have to follow our law our bear the consequence.

As a parallel, fresh raw milk cheese is not allowed to be sold in the US despite being very popular in France (and tasty!). That means French cheesemakers need to limit which cheeses they sell over there, even though their local laws don't restrict them.
