I wouldnt call it a hyperbole. At least not an intentional one.
I admit you have a point here.
My understanding is: if its on the chip theres a way to access it easily via a software backdoor.
But then, i am not familiar with A7 architecture. I am also not a computer scientist.
People who r agreed with me though.

You are purveying FUD with regard to Touch ID, based admittedly on no evidence at all.
The rest of your treatise about the government and financial institutions has nothing to do with Touch ID.
