Yes, because there is a basic assumption. Those projects aren't consumer-facing games. Those are hobbies. You know it and you are simply arguing in bad faith. I know actual game developers who released their games for free or under a pay-what-you-want model. They refuse to do so again because they can't support themselves by doing it. I am a game developer and I won't release my games for free because I need to support myself. There is all the data you need. Find me other data saying otherwise.
