general principle was there before apple. but for sure they do cook a 'book' or two, as one of the most wealthy companies in the world, without any strong sense of morality (not saying lack of it, just usual corporation as many others).
If you can invest for example 500 millions USD in bribes to gain 5 billions per year in not paying taxes, that's a damn easy decision for some CEO. And those fictional 500 millions will get you quite far in these times, where lobbyists in capital cities in both EU and US are not even illegal (in my opinion should be shot in sight), but just part of daily life.
