First, thank you for your support. Second, people are working two jobs to sustain the development. Most indie projects can't sustain a TEAM. Rent, food, bills, it adds up. Perhaps after you get an idea of how much cost a sizable project requires, you would have a different opinion.
I can't speak for the yandere guy, but most devs lack experience, resources, or both. Time and the spirit of trial and error are the only resources left.
