Thanks Daniel for chiming in!
  Just to recap, the original cover art featured a
synthesis of Tux and
 the famous portrait of Ernesto 'Che' Guevara by Alberto Korda. Reason -
 both are black and white icons with three letter names. I thought it was
 amusing, and only very mildly subversive. Is free software
 revolutionary, in the broad sense of the word? I believe it is. 
Yes, but this particular outreach component is, as you have also pointed out
below, primarily about art. Hence the dilemma.
  However, some of the US-based contributors felt that
this modified image
 would cause trouble for their careers, at the educational institutions
 where they work. Yes, really, 45 years after the Bay of Pigs disaster.
 So the image was changed but the title stayed, becoming somewhat
 orphaned from the cover concept. 
Point well taken. Yet, this in and of itself could've also detracted from
the core idea of the project which was and still is art.
  I personally don't care what it's called -
it's the music that matters.
