"The EU" will probably never demand access to Apple's data. The EU usually passes legislation that has to be adapted by all member states (where, usually, the EU decision is the minimum that the states have to implement, some do even implement more).
Still, all those requests will be by member states and involve different demands.
So, probably, even in the EU, they will say "FU!" to some and not to others.
Apple might not care about Iran or other smaller countries, but how is it going to deal with big market like China, India, EU?
