I think "Extreme conditions" is often a false security.  The Facebook - Cambridge Analytica scandal should rember that.
I prefer a situation where I know I'm actually exposed to possible monitoring, to force me to choose the countermeasures that I think are more appropriate.

An anonymous mode is unfortunately pointless if users don't understand the implication of privacy and its value, and go on doxing themselves publishing personal informations. A little awareness is needed, before the technical tool.

Btw, I agree that this is a important topic that deserves more attention.
