Apple will argue and complain in the EU, but if they cannot win their case I am sure they will do as they are told, rather than pull out and lose all those EU-profits. Europe is a (slightly) more valuable market than China, vastly more valuable than Russia, and Apple was willing to compromise its sacred stance on privacy to keep the Chinese and Russian markets.Or Apple will just pull all of their devices out of the EU while the rest of the world gets to enjoy Apple’s products.
Granted, China has additional leverage via Apple's addiction to Chinese manufacturing. But the EU-demands are considerably less questionable from a moral perspective, if they can be considered questionable at all. If Apple is willing to bend over backwards in China and Russia, doing a little curtsy in the EU is a small concession to secure the profits at stake.
I think it is great how Apple is standing up against Facebook, tracking and the like. But I have no doubt that profit is their only constant guiding principle, and that Apple will adjust or abandon their ethics whenever necessary to protect their profits.
