I'm not going to trust you. The EU has shown time and again that it is perfectly capable of dealing with asshole companies and Norway, even though it isn't in the EU has enough standing with the Union and the Nordics separately to get them to take this serious.

There is probably a reason that you are not a Facebook exec, and no disrespect to you but you are clueless about how large companies interact with the law. They'll scream, they'll sue, they'll haggle and they will delay but ultimately they fold. The same has already happened to big telco's, many large IT companies, industrial giants etc, FB is no exception.
