It appears that all of Apple's techniques are legal by U.S. law, though some politicians have said that corporations going to extraordinary lengths to avoid paying income tax and that they are violating the spirit of tax laws.
It's sick how "violating the spirit of the law" is only one-sided and left completely up to their whim. So these politicians are saying the "spirit of the law" only matters when it affects them. What about protecting the "spirit of the law" of the constitution, or pretty much everything else that they touch and destroy?
Our sad country!
I wish Abraham Lincoln would come back and kick their asses!
