Quality of a language's community does affect the experience of using it. PHP is great example to use though - just because people are doing nefarious things doesn't make them unpleasant people.

The difference between this and the PHP case is one of economics. Economic input gives you influence (usually). If people who's approach to life you don't agree with assume influence over the direction of a project, that can be a source of worry.

I'm not sure I think it would be in this case, I think a source of finance is probably going to outweigh it, but I see the logic.
