A missed point...
Generally taxes are used for public benefit (yes I know there are lots of exceptions and there will be snarky comments about this) - but in terms of providing and maintaining roads, law and order, fire protection, healthcare for staff, waste disposal, etc. Irrespective of the rights and wrongs of this case, Apple as an income and profit generating entity is quite happily using these services and benefiting from them, but is not willing to pay its fair share.
Simply from a social good perspective and not from a "they're all a bunch of greedy bastards" they deserve to pay taxes to make their fair contribution across each European country in which they operate.
Of course, the governments concerned could always withhold collection of waste, block off roads, ignore any 999 requests originating from Apple until they do pay.... :-)
