The ones which are responsible are Apple and their shareholders if they are found guilty, and do you really think Apple will raise prices again by quite a bit in Europe, don't think so because more and more people think iPhones are getting too expensive in Europe, even more people will go somewhere else, read Samsung or others.
Don't be surprised if services take even longer to come to Europe now. Not providing services for Europe (or delaying them) will be the likely way they choose to eat up the addition cost, without raising the price of their devices. Most Apple services are paid through iOS device sales.
