Rude and entitled behavior is of course unacceptable. That said I think the project developers and maintainers often share a large portion of the blame. Most projects are very keen on telling you about their amazing new features and the awesome stuff you can build with it. What they don't do is properly document limitations of their software or honest comparisons with competing solutions. Additionally many developers overhype the status of their project. They'll call it production ready, mature, claim it has a vibrant community and ecosystem and so on, when these things really bend the truth. That builds expectations and running into critical, well known bugs that don't get fixed can be extremely frustrating.
