The point of the comment is that "fix it" isn't an option when the maintainers won't even look at your bug fix.
I'm VERY appreciative of FOSS but it does seem that if you are going to maintain a project then it isn't unreasonable to expect that you'll at least consider a PR, and give some reason if you choose to reject it.
Not to saturate this thread with my varying opinions, but default rejection with reasoning of stability could be assumed. Anyone who has worked in code long enough knows seemingly obvious changes can have unintended consequences. If a company is making money off my FOSS code then maybe they can test their fixes for an eternity before I incorporate it and it potentially breaks some other companies code.
