Artist time costs more money than software licenses do, and as the open source software isn't generally good enough for their needs, using better off-the-shelf software that have fairly decent and flexible plugin APIs is good enough for them. A lot of the code VFX studios have is proprietary (as in unique to the individual studio who wrote it) plugins for host apps like Maya, Katana and Nuke, and shaders/integrators for renderers like PRMan and Arnold.
