This is a somewhat idealistic/naive view. If your project is even mildly successful and you get motivated to keep contributing to it more and more and form a strong community soon the leechers arrive. They start demanding more and more for literally nothing in return under the pretence that it's in the best interest of the project to add the features they want and to accelerate development.
It soon becomes exhausting to deal with them on a regular basis while still feeling good about contributing. People are faster to demand rather than appreciate and you start wondering what the point of all this is.
So yes, if you end up painting something that's like a high school project, sure, it's easy to leave it on the wall and not care. But if your painting starts getting displayed in galleries and there's a little "demand" for it, everything becomes a headache.
