Sometimes companies just make it worse for themselves when they drag things out, but in this case I certainly understand Apple's motivation to drag it out until they get a better outcome, either paying a lot less or nothing. Well, actually with attorney fees they will still pay a good amount if it actually takes years to settle.
Apple has deep pockets and so does the EU, but the EU has a few other tricks up their sleeve to make Apple and Ireland comply with the ruling. Just deep pockets from Apple won't save them this time.
