That's the key. There is no news here because every phone running every OS is back-doored[1]. Completely, totally back-doored. This includes every single phone "replicant" has ever been installed on.

There is a computer in your phone, that you cannot access, running a closed source, proprietary OS that your carrier controls, that has (in many cases) DMA access to your "actual" phone.

Your carrier has total control over that computer in your pocket.

Game Over.

[1] With the very tiny exceptions of calypso-based motorola phones running osmocom and possibly the neo freerunner phones ... but I could be wrong about those...
