This doesn't make any sense. Apple has a pile of cash hasn't spent or invested = they have given away free product?

A debt never called is the same as giving something away for free, yes.

Technically they can still call the debt, but the question remains outstanding: What do you have that they would want in return? The answer is effectively nothing, and increasingly so.
