One could say that they are giving something back, by using those profits to develop ways to make computing more accessible and useful, something they're better at and more willing to invest in than anyone else.
Let me repeat that back to you as I understood it.
What you are saying is Apple (and their work) is $deity's gift to the world so they don't owe anything else regardless how many billions of dollars they make from it.
People in parts of the world that need help to survive or thrive more than a meager existence, aren't helped by Apple's pretty software UI and hardware design.
US society has already decided what Apple owes back each year, via the IRS. I don't see why it's fair to expect them to dispose of more of their shareholders' money than some other companies in the same position. It's not as if their shareholders would reach a consensus about an unrelated social problem to solve, much less make an empty gesture towards solving (charities can't fix the free rider issue, which is why they almost never get enough resources to actually succeed and shut down).
Personally charitable & publicly charitable are two different things. Unless you know something the rest of us don't, I would be careful passing judgement on someone you only see in keynote speaking environments.
What a silly excuse to give nothing back - both Apple and Jobs individually are sitting on ridiculous amounts of money regardless of what their shareholders do with their own money.
One might say they owe something back.
With the extreme loyalty of it's userbase, they could set some very nice examples.
Why Steve Jobs isn't personally charitable with $5B in the bank is a rather depressing mystery.
