Seems like both sides are villains here. Apple is a villain for initially refusing to release a statement saying "Carl Sagan does not endorse our product". Carl Sagan is a villain for suing when they changed the codename to "Butt-Head Astronomer".
(Aw crap, am I going to be sued by the Carl Sagan estate for calling him a "villain"?)
