firmware of RPi can be changed: https://github.com/Hexxeh/rpi-update /
https://github.com/Hexxeh/rpi-firmware

next to that the official firmware of RPi is closed source. you have
no idea what it does

and RPi is build by a small company in the UK, very likely that they
will accept a generous offer by the FBI/NSA/USA.

solder your own shit if you want to be protected on this level.
