I’m evaluating spark at the moment. The license states that it includes icons that are free for non-commercial use. It is unclear to me what this means. Can I or can I not use spark for commercial use as a result of this license? It’s my understanding that spark itself is a non-commercial project and is therefore granted a license to freely redistribute the icons as part of the project, I should therefore be free to use spark for commercial purposes. Is this correct or is spark a product that can be used for non-commercial purposes only as a result of using these icons?
