Apple makes $21 million (in profit, not revenue) every 3 hours. It makes sense for them to make this go away to avoid damage to their brand more than anything. Also, considering how litigious Apple has been lately as an opportunity cost of the use of their legal team fighting this sort of thing in court is probably not a good idea.

More so, the money they would pay to the Swiss Federal Railway will come out of a heaped up mound of money that Apple would have trouble bringing back to the US anyway (due to tax implications). Overall this is a fairly sane move on Apple's part. Get it out of the way, and move on.
