1. I only run Linux where possible, and I install myself (and I realize I do not control the BIOS, etc). OpenBSD would probably be even better.

This is a dangerous trajectory and we'll hear "But think of the children!" or the good old "If you have nothing to hide you have nothing to fear." ad nauseam.
We've been over the fallacy of these statements already, so I will just quote Benjamin Franklin: "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." (Although apparently the original context of that quote was not about Liberty at all.)
