If you jumped through all the hoops Apple did to try to evade paying taxes, you should know you're playing Russian roulette. Apple knew going into it that they were intentionally evading taxes - hell they hired several special tax accountants just to manage the cf required to make all this work. They were just assuming (hoping?)they had enough grease to keep the loophole open - they were wrong.

I believe they even called the liability out in their s1 filings, but I can't currently check.
