Yes but think of this. With Blender at least they can make the modifications themselves and use it while waiting for it to be up-streamed. They could even keep the work in-house.
On the other hand Autodesk has no open source.
So this studio would have to make a request to Autodesk to include this feature. Then wait for Autodesk to make the change and then wait for a version to include this change.
With Blender they can create their own fork and Blender will merge their work if they like the code.
One business model they wait for Autodesk and the other they make their own modifications to Blender.
I would conclude they are on the right path.
With all the money they save on licensing fees they can hire developers.
No more dongles.
