There is not a duty but there is an image and quality issue. Something many open source projects suffer from and should not.

And even mentioning that results in "fork it if you're not happy" which immediately turns everyone off who's had to maintain a fork to fix a minor issue in something before. And anyone who can't fork it is being told to go to hell.

Everyone needs to quite frankly get off their high horse, crank the ego down and listen to users. Because you're damaging open source with the attitude.

30 years ago, things were better. They got a lot worse, particularly since github appeared.
