"If you're going to leave one proprietary, commercial & licensed platform for another, then really what's the point?"
The point is using a complete UNIX operating system that works with any Unix code using standards like OpenGL, but at the same time, is respected by manufacturers of hardware and supported by service providers.
Half our computers(lots of them)in our company are Linux, half of them Mac. Using Unix means we could inter operate between them very easy, not like using Windows forcing DirectX(in theory you could use OpenGL, ha!).
Using Linux means we have total freedom in what we could do. We are outside USA, not software patents here.
