> Why do some users feel so entitled?

As a user, I have no longer a way of knowing whether an "open source" project's main developers are doing stuff in their free time or on company time. So, I don't see anything wrong with asking for features. Asking for features is how software evelves, whether closed source or open source. If you have a problem with it, put a disclaimer "unmaintained" in the README.md (because not wanting to tirage requests amounts to not maintaining the software).
