You might be right, although author responds that concern with considerable detail here:

  But let’s step back here. I am using the word in its 
  everyday, loosely overloaded sense.  As in, you telling 
  your friend, “you are such a !@##$ sociopath.”  I want to 
  stick to the term for two good reasons. One: Hugh 
  Macleod’s original cartoon which inspired this series is 
  too good to give up. Second, distrust of communities and 
  groups, and a stubborn individualism, are the main 
  personality characteristics here (and this position is 
  not original to me; it is derived from William Whyte). 
  Words like “player” or “enlightened” (two suggested 
  alternatives) don’t cut it.
