If demanding taxes to be paid is "stealing", then what do you call it when somebody uses resources they aren't paying for? You know, if a person feels entitled to exploit the generosity of others and gives nothing back, we call him a parasite and suspect him of being a psychopath, so what kind of person is Apple? And if Ireland gives unreasonable tax benefits to certain, big corporations, does that not skew the market that is the very foundation of the EU (and which, incidentally, is the reason why Ireland wants to be a member)?
I have a good deal of respect for people who honestly believe in freedom and free market capitalism (even if I don't agree), but what you are talking about is just nonsense. The free market only stays free in any meaningful sense, if everybody genuinely agrees to follow the same rules, and that includes taxation and competition.
