I have to wonder why you, and many others, are so concerned with what language other people use?
As I mentioned in a previous post, I have a graphics app (Poser) that has a scripting interface that unfortunately uses Python. And if I want to do some moderate modding in Civilization IV then I need to learn some Python (the easy stuff is modifying XML files and the really hard stuff would be writing your own AI in C).
Anyway, the point is that the decisions of others do affect me and that is why I should be concerned about it. I mean, I wish I could easily MOD Civ4 using Perl. :-/
Update: Fixed a typo
