So, it means, without my knowledge as a computer user, I have a HIDDEN
OPERATING SYSTEM running under my nose. Securitiwise, it is like
running MS Windows notwithstanding I am running Devuan ASCII!

With all this, a tinfoil hat is completely useless. I need an armoured
hat with the same thickness like a war tank, but will it help?

Hiding a complete OS integrated on the main processor's silicon die,
and to add insult to injury, complete with a dedicated processor,
filesystem and all!
