      This is, IMO, where even one of the most cited
        interpretations goes off the rails.
      

      Don’t assume malice where incompetence can suffice.
        

    Except that today's network is filled with deliberately
      malevolent entities who are sending traffic that is designed to
      act against the interests of the destinations of that traffic.  
      And there's a such broad spectrum of such malevolence that there
      are essentially no white hats out there - only hats that look
      white if the sun angle is just right.
    (and sure, some of the malevolent actors are incompetent, but
      they're getting more competent overall with each passing day)
