So yeah, the EU is bound to be a big number but it isn’t 25%. The biggest economies in the EU are Germany, France, Italy, Netherlands, Belgium? Big countries outside of it but included in Apple’s “Europe” catagory include the nordics, UK, Switzerland, Turkey, UAE, Saudi Arabia, Kuwait and probably something else.
Even if the EU makes up half of what Apple calls “Europe.” A fine of 10% of worldwide revenues is way beyond what the EU contributes to the bottom line. There’s no way Apple wants to take the nuclear option but if the EU threatens them with big enough fines they might think about it.
