Yeah, I see your point, and I have to admit that it's been kind of a turnoff as I've been considering DDS for my own company. The other thing it does is create incentives to create optional paid add-ons. Then you find the support company talking out of both sides of their mouth, because they're trying to sell you on how great it is that the underlying standard is free and open, but simultaneously trying to sell you on how their paid, proprietary add-on is absolutely crucial. It creates an unease, where you're never sure where the border between paid and free will lie.
