The only way to really be sure that you control your devices is to use free/open source software.

  Not really. FLOSS is about being in control of your software (being able to legally modify and distribute things), not making any guarantees about software behavior (including security). Indeed, source code availability (much weaker than FLOSS) is very useful in software analysis. Nonetheless, while in most cases this is just tedious and boring work, one can still validate proprietary binary blobs. Obviously, that only applies to countries where reverse engineering is legal.

    If you can't modify/replace the software on your device, do you really control that device? In my opinion, validation/analysis is a necessary but insufficient condition for control.

      One can modify proprietary blobs, too. It's just insanely more complicated due to necessity to reverse engineer things and not universally legal.
