I think the solution is for people to understand that open source goes both ways. Unlike what this post says, users don't owe maintainers anything, but maintainers also don't owe the users anything. If I build something cool and share it freely, why should users expect anything from me? Why should you expect me to maintain it or add the features you want? I think we need a mentality change where less is expected from maintainers, unless funding is arranged.
After all, it's free and open source. No one is forcing you to use it. Don't like that I'm not actively developing it? Submit a PR or fork it. Isn't that what the original spirit of open source was? I think that open source has been so succesful and good that we've come to expect it to be almost like commercial software. That's not what it is.
