Lol indeed: throw their execs in jail when they transit through a country with which they have an extradition agreement (plenty of precedent for that), freeze or seize their assets, block them at the ISP level (ISPs would have to play ball unless they themselves would want to be come a target).

The idea that some crap company outranks a nation state with millions of citizens is ridiculous.

Also: even though Norway isn't part of the EU (though it is in Schengen) they could bring a case in the EU courts and have Meta's assets in Ireland seized. That would really hurt if the court allowed it.
