I decided to choose a closed license, but make models free available for everyone. Why did I made this decision? For my models I'm investigating a massive time effort in my private time. It is my decision to spent my time for this purpose and it is also my decision to have full control, how I share models with the community. As soon I would open my designs to remix it, share it, etc. others would make use of my effort to high-light themselves without having the control from my side anymore. This happens for example at YouTube for some influencers who are stealing the show. For me it is not about to be influencer or to make a show out of it. I'm also not ok others are doing that for me without any tribute for my effort! Please keep me informed if anybody is selling my models, which is not allowed from my side!
