Agreed. I think this just revolves around clear communication and expectation setting. Just too often it is all too implicit and ad-hoc, where frustration easily brews on both sides.
It's like wet towels and mildew. Lol. Don't wet them if you're not going to dry them or hang them up. (Disclaimer: I didn't heavily think through this analogy.)
(though open sourcing project and not accepting PRs or even issues is fine, if it is actually maintained)
