I think it's just what you're used to. When I first saw a Mac I thought it was crazy the way all the windows were white and the text was black. All the white burned my eyes and I thought it was a terrible decision. But obviously everyone can cope with it just fine and it became the norm. The "oh my eyes" hyperbole about green on black is because people aren't used to it and it is in stark contrast to what "normal" is nowadays--but just use it for an hour and you'll be just fine. I personally think it's a little less straining on the eyes because there's less light hitting your eyes. Lately my terminals and emacs always use a black background.
