The Great Flat.

I work with many skilled professionals who have spent many years honing their craft in the visual effects industry. One in particular wanted to build an awesome matte painting workflow in Blender but found it lacking some key features. Since Blender was open source he figured he could just hire a few developers and then license those tools to his colleges. Not going to happen. The not-so-open Blender big wigs didn't think that aligned with the Blender prerogative and offered no help. Consequently, they lost an opportunity to provide a very powerful feature set. Does that seem right to you? By discouraging monetization it eliminates the product's ability to really nail the specifics, and all that remains is a general mush.
