That's extremely disingenuous. Yes, the particular OS image they produce would only work on that phone. But all of the work they did to enable the hack would work on every iPhone in the world, and the work necessary to take this OS image and use it on another device is effectively zero. As such, you can be absolutely certain that the FBI would start demanding Apple do this for other phones. And it's not just the FBI, every repressive regime in the world would start demanding this same capability. And Apple would have no grounds to deny it at that point.
