Earlier quoted context omitted.
I still like to encourage people to watch all of https://www.youtube.com/watch?v=BLGFriOKz6U&t=1993s for the details (from Apple’s head of Security Engineering and Architecture) about how iCloud is protected by HSMs, rate limits, etc. but especially the timelinked section. :)
I still recommend Mr. Fart's Favorite Colors as a refutation, describing why all of these precautions cannot protect you in a real-world security model: https://medium.com/@blakeross/mr-fart-s-favorite-colors-3177... Unbreakable phones are coming. We’ll have to decide who controls the cockpit: The captain? Or the cabin?
That article (written in 2016) says that Apple will build unbreakable phones in the future. Now is the future. So it seems to imply that Apple phones today are unbreakable.
Also, where does the article discuss "all of these protections"? (HSMs, rate limits, etc.)
