Yes, of course it has a lot to do with information hygiene. We need to be more particular about what we let into our minds, we just don't have the tradition for it yet. Browsing facebook is more like taking a walk in a dystopian junkyard than a forest, and a sign by Apple saying "you might be browsing a junkyard" would just add to this dystopia. This is why the proposal is to design better spaces for mindless browsing, since we apparently need it.
