I can definitely understand that sort of reaction for developers, especially if you're talking about small open source projects... those are projects which usually scratch the itch of the developer, so feature requests are definitely going to be an uphill battle if they aren't interesting to the developer (for some definition of "interesting" which might mean "actually useful", "fun to code/play with", "that code is shit and needs refactoring anyways", "suggestion in the form of a patch/pull request", etc).
I think users see software development effort as zero sum; if someone is working on a feature they aren't interested in, then someone isn't working on other stuff they think is important. It's a well-known phenomenon that often comes up when someone talks about the complexity of Microsoft Excel (in the form of the 90-10 rule)... users don't see the bigger picture and only care about their own workflow and how changes impact them.
The easy solution is to simply not give a crap about the opinions of other users of whatever software you use. They don't have your best interests in mind either.
