> Why would you ever login to a sensitive account on a device you don't own and have root on?
You mean like the phones that everyone uses with banking apps?
I don't. No financial transactions for me on something so easily lost or stolen, with any number of possible exploits lurking out there. Phones should be treated as compromised from day one.
I have my problems with this as well, but at least no one else already has root on my phone.
