1) Apple is a publicly traded company, and as such, has a fiduciary responsibility to its shareholders to use any legal means to minimize its tax liabilities.
2) Ireland's current tax laws that Apple is taking advantage of may or may not need to be updated based on how things have changed since they were first written. Whether they should be or not is a subjective matter that can be discussed by all stakeholder parties, and any changes made need to be in line with other Ireland and EU governing policies.
3) However, the EU simply cannot retrospectively change Ireland tax laws on what they think they should have been. The only relevant question is did Apple follow existing Ireland tax law correctly? If so, they cannot impose a retroactive tax on Apple. The EU does have leverage to drive changes to Ireland's tax policies moving forward, though.
4) This type of ham-handed extra-legislative action by the EU is exactly the type of thing that got the "Brexit" stuff started (and even passed). If the EU bureaucrats continue to overstep their boundaries and supersede the legislatures and courts of the member countries, they're going to continue to find themselves with fewer member countries (and more to the point, the net tax-paying countries that can both afford to leave and have the biggest impact when they do).
1) Sure, but legal means within the law.
2) No ireland made an illegal deal with apple it was not authorised to make.
3) The EU heavily funds Ireland compared to it's contributions and would suffer if the EU cut the funding apple owes. Ireland very much needs to claim tax from apple to avoid heavy penalties. The EU very much is LAW.
4) The UK narrowly won an exit from the EU. There are doubts the UK can make a deal without another referendum, The EU is not over-stretching it's beneficial for all member states to charge tax at the correct rates as everyone in the EU gets that cash.
You see to think that apple has done no wrong when they have been told the deal is illegal and they owe taxes. It's not retroactive, it's their current unpaid tax bill.
Sure you might like apple products as do I but the company stinks and makes terrible deals that squeeze the poor and **** anyone who might stand in their way. Apple the corporation does not care about you so don't defend them when they do wrong, that's beyond moronic.
