The only people entitled to say how open source 'ought' to work are people who run projects, and the scope of their entitlement extends only to their own projects.
Just because someone open sources something does not imply they owe the world a change in their status, focus and effort, e.g. from inventor to community manager.
As a user of something open source you are not thereby entitled to anything at all. You are not entitled to contribute. You are not entitled to features. You are not entitled to the attention of others. You are not entitled to having value attached to your complaints. You are not entitled to this explanation.
If you have expectations (of others) that aren't being met, those expectations are your own responsibility. You are responsible for your own needs. If you want things, make them.
