I disagree. If you discover that a bug that makes an open source library unusable to you, after spending time on learning and using that library, and the authors close the bug as a wontfix, I think being annoyed is quite reasonable, even expected.
It's open source software. If you discover the bug, have written a failing test that demonstrates it, and a proposed solution to it, then maybe you can be annoyed when the authors close it as wontfix.
Otherwise OSS is pretty much as-is, where-is, with the exception of very widely used and corporately supported projects.
Not really no, you got the support you were willing to pay for.
If that type of thing annoys you then you should restrict your use of open source projects to those backed by corporations with a paid support business model.
