> If you are going to use someone else's work in order to make something that you are going to profit off of, I believe that original author should be compensated. And should also be able to decide they don't want their work used in that way. You're posting on HN. Are you expecting a check from YCombinator? > Regardless, copyright is about distribution. If the a model trained on copyrighted material is considered a copy or derived work of the original work, then distributing that model is, in fact, copyright infringement (absent a successful fair use defense). I'm not saying that's the case, or how a court would look at it, but that's something to consider. The government is what ultimately decides what copyright means. And if the court wouldn't look at it that way, then it's not "in fact copyright infringement".
