@ThreeBadgersInATrenchcoat You say yourself that this "myth" is actually true and then "debunk" it because some people understand it wrong? This makes little sense. Linux is more private ootb because as opposed to windows and macOS it does not collect any user data (unless you tell it to). This is a little generalized but basically true I would say.
What users then do with it is another story and caution with apps is advised but privacy-conscious people will be aware of this, no?
