I might even say that if you're giving code away, you don't owe users anything. But you might also have goals for your project that would benefit from trying to attract, on onboard, or otherwise please users.

The idea of spoon feeding simple but incredible solutions for free can be very rewarding for maintainers, and can also generate a monetary reward as well. There are projects that I happily donate to because they create value for me. How many terms of service have you read of apps that you pay for? It seems that many apps you pay don't just take your money, but your privacy and rights away too. Developers creating something in the open can inspire and help make communities of people working on a shared goal, that attracts quality individuals from all over the world to help. It brings people that are excited about your goals and that came to your project because it was something they could find and appreciate. I'd say, you don't get the same from closed-source software. You also can't achieve the same by being an asshole to potential contributors just because you feel like it. Sure, it is an option, but if you want to actually build something... not just for you, but a dream, then it is a bad choice to not try to build a healthy community.
