You're right, I did. But looking at the article you cite I see
experts boast about successful access to iPhone data in instances where the NSA is able to infiltrate the computer a person uses to sync their iPhone
which is not quite the same as what you wrote. In particular, the story suggests they have to be targeting you specifically before your phone is at risk. If all that is right, then the NSA wouldn't be stockpiling hundreds of millions of fingerprints just by idly scraping the Internet the way they do with email and call records. And if they do want to target you specifically, well, most people leave lots and lots of fingerprints in all kinds of public places, retrievable using nineteenth-century technology.
