> the Snowden leaks have shown that the NSA has total control over all iPhones

You mean: had total control over all the original iPhones that they could get physical access to. (back when jailbreaking was extremely simple and common)

Where does the "physical access" part come from? And if that was the case, why would it be impossible now?

From the slide on your very link: "The initial release of DROPOUTJEEP will focus on installing the implant via close access methods. A remote installation capability will be pursued in a future release."

Basically how it worked was they jailbroke your iPhone and installed spyware on it. Is it quite likely that today, 7 years later, they have a remote 0day to do the same? Absolutely. But there's no proof that "the NSA has total control over all iPhones".
