It doesn't have to be ill will, or even will. Something like JACK is a component of a system. Maintaining this component as open source is fairly simple -- but capturing and sharing the understanding the complex interplay of components and the tradeoff needed to achieve certain ends in the wider system is really, really hard. Linux might be free and open source software, but it's not a failure of anything that it doesn't come with a free systems administrator education.
