Blender is probably some of the most user friendly open source software. It was originally a paid software developed by a studio in the Netherlands. It was so well loved and widely used that when the company collapsed the customers raised money to buy up the rights to the software and licensed it as open source. They also set up the Blender Foundation, so it’s less like Audacity where it was put together by a small crew making occasional updates, and more like Firefox where it has the full backing of a non-profit. It’s getting more user-friendly with each release, but it’s still not as easy to use as something like Maya.
