>The first has almost 0% chance of happening. Apple will never bail out its customers for insured deposits, as that money is guaranteed by the FDIC. Why would they effectively "donate" money for free to the FDIC?
Yes, this was a hypothetical based on a situation in which these accounts weren't protected by FDIC, either by design or some problem with the FDIC. Apple isn't going to donate money to the federal government. But I could see it donating money to its customers as an attempt to retain the value of its brand.
>The only universe in which that happens is the one in which the FDIC somehow is insolvent and the federal government abandons the FDIC and the cascading effects of the latter (which would almost certainly create a national if not global financial crisis that makes 2008 look quaint) somehow don't affect Apple enough that they could use their additional cash on hand to pay their entire banking liabilities. Which is pretty unlikely, given that most non-banking companies don't have cash reserves that large that they can dip into at a moment's notice. Even Apple, the world's biggest company, has "only" $50B in cash on hand as of last quarter, which sounds like a lot but would not be enough to weather that kind of a crisis and still be able to make depositors whole even if they felt that it was their responsibility.
The FDIC might not have the money to cover a failure as big as Goldman Sachs and the cascading effects (a quick Google search says the FDIC has $128b in the insurance fund and GS has $110b in consumer deposits, so it seems close at the moment). The big question is what would the US government do in response to a failure this big. Would a polarized and split Congress want to or even be able to compromise on a rescue plan? What if the issue is specifically at Goldman Sachs due to corruption or some other crime rather than an issue with the overall economic environment? Like I said, the odds of this situation are extremely low, but so are the odds of Apple accepting the destruction of their brand.
