Hello Linuxdsp!
 I suppose you may have a point there. But in open source projects - or non-commercial projects - it's more probable - with my experience - to get feature requests granted for features, that concern only a minority, like blind or other wise disabled people. There are of course people in closed source development, who say, that they are sorry, can see the reasons and it being good, but the management won't fund it.
 Well, but that's just an aside. Generally, yes I agree, you stand a chance in both worlds and there are always open and closed minded people or people focused on only one goal.
 Warm regards
