This EU ruling was no news to Apple's lawyers. Cook was pre-warned.
Apple's lawyers have, based on FIAT, BP, and other rulings, told Cook this is a lost case. Hence, Cook decides to play is last card: The Political Card; "Appealing to Irish politicians, being rude, raising the anti-EU feelings, f... those bureacrats, Ireland has autonomy do do what they want!"
Cook has shown the weakness of his position.
And Irish politicians has a crash course in EU-law in front of them.
Apple will have to pay.
