And this clarifies the source of your confusion. The D programming language is an open source project, not a for-profit company. D is not the language you're looking for.
There are 3 years since C# is also open source project. Last week 72 pull requests form 24 contributors were merged on ~master. And this is only for Roslyn (the C# compiler).
The difference (at least for me) is that contributing to C# is a no-brainer. Contributing to D needs an advanced degree in computer science. Using the information on the D wiki didn't helped me until now to successfully compile and test a fresh copy of dmd or phobos.
