While I agree with most of what you said, you have to remember that a) BM was there long before I started playing around with WS, it's the main project. B) The fan base for WS is a lot smaller than for BM and C) WS makes no money and I'll never be able to sell it officially because the software (engine) license doesn't allow it.
Let me be honest with you, I might prefer WS a bit more than BM myself. It's a bit rough around the edges, but it's fun, and I will definitely come back to it, but BM has priority at the moment.
