With Blender initially released in 2002 as a free 3d modeling, rendering and animation software, it disrupted the market because it was dominated by commercial software which would cost you a fortune to buy it. It is very interesting as the community developed software has been growing significantly, it forces the software company to change their business model into yearly based license. Definitely getting more affordable to some, but still, it doesn't stop the community to develop even better software to share to the world.
