You know, a "made with" blender film just won an Oscar. I bet Blender devs also have to make a living and I doubt they work for free.
Like where? The Blender Foundation doesn't do any aggressive marketing...
If it was easy to get the required funding, wouldn’t Synfig be in a position to rake in funds and hire people to improve Synfig?
Survivor bias backed examples are not a good argument.
Just because a movie made with it did well, doesn't mean Blender devs get paid.
