To a consumer, the difference between a commercial product and an open source product is price, security, dependability, and freedom. Commercial products will cost as much as the company that controls it can get away with charging and if they can charge a lot they will happily price out many people if that still makes them money. companies will also take a commercial product and add anti-features, spy on their users, prevent anyone from building off of the work to create something new, disable/discontinue the product at any time for any reason, etc.
To the consumer open source is much better.
If I want art and it comes from open source tools, I can use those same tools to modify/copy/customize that art according to my needs or learn to create similar art at no cost.
If I want art from a commercial product it will likely be DRM filled trash and I probably won't be able to use the same tools to modify the art or to create my own similar artistic works without being exploited somehow.
