I know all that. My beef is with using the term "giving money BACK to the shareholders". The money in question did not come from the shareholders, but from people who bought their products. So call it what it is: giving money to the shareholders. "Giving the money back" means that they received money, and now they are giving that money back where they got it from. And that would mean giving it back to the people who bought their products since they are the ones who gave them money.
No, I'm not advocating that they do that. If they want to give that money to someone, it should go to the shareholders. But that is not "giving money back to shareholders", its just giving them money.
But the thing is, Apple received capital from shareholders when they went public. That is why it is termed as "giving money BACK to shareholders."
