Have you adjusted for (what I assume is) the fact that most game developers are sighted? In fact, have you checked whether there even exist any not-even-formerly-sighted game developers? It seems like that would be a tough row to hoe even by the standards of blind-from-birth life.

That aside, I'm really not seeing the problem here. You're going to complain about people being altruistic towards the visually impaired? Really confused about your thought process.
