I assume that, being a 6502, you know better than what you are writing, but I know I shouldn't assume.
1) Apple pays taxes as required in the countries where it does business. That applies both inside and outside the US.
2) After paying taxes in such countries above, Apple has excess currency (it's a profitable business, after all).
3) Apple moves that money around between countries that are outside the United States.
4) Apple chooses not to bring those currencies back to the United States because the repatriation taxes are unpalatable.
In the above scenario, Apple is paying all the taxes it owes on earned income. What Apple is not paying is a repatriation tax that it does not have to pay if it does not repatriate foreign currency. If Apple is earning *interest* in some country where it *stores* its money at a favorable rate, that's just plain common sense.
Separate point: Apple does not "tax" its developers. It charges a fee for the right to sell in the App Store. In exchange, Apple provides the infrastructure to make those apps accessible to customers: advertising, sales, logistics. This allows the developers to focus on developing.
As to Woz 50% income tax, that's simply not correct. the maximum for ordinary income is 39.6%.

And if Woz is paying that on his total annual income (including dividends, capital gains, etc), as another reader has observed, he needs to fire his tax preparer/lawyer.
