If a company wants to sell services in EU, they have to follow EU guidelines.
It doesn’t matter if the company is based in EU or Iceland or USA, that makes no difference. Same how they have to comply with USA guidelines if they want to sell services in USA: Upcoming Sales Tax Changes for EVE Online Purchases in the USA & Canada

P.S. Iceland is not in EU, Game prices are set in Euro and USD, CCP Games have a studio in London, UK, which probably means that English used in general forums would be “British English”.
