> If you re going to be paranoid, because you attack children or sell drugs, why the hell do you buy phones in the first place !?

While the rest of your comment is accurate, this is disingenuous. There are plenty of valid reasons to have concerns over this besides those drilled by the powers that be.

Besides, it's still reasonable to want to reduce your potential attack surface. Sure, federal agencies may root you if they really want but that doesn't mean it's pointless to avoid OS-level preinstalled backdoors from the manufacturer.
