One thing that comes to mind is gnome's refusal to implement type-ahead in nautilus and the gtk3 file picker. It's a very popular and visible issue that I won't get into here, but suffice to say that there are a lot of people who would really like a more traditional type-ahead. There aren't any specific pull requests I'm aware of although there are forked versions available. When asked about it the developers involved just say "no", and any attempt to work on a compromise or discuss what would be necessary to include a flag somewhere deep in gcnonf to revert the behavior is met with a resounding "we're not interested in that feature". Which is fine, but don't keep other people from implementing a feature that they like just because it doesn't fit in with your vision. That attitude seems pretty endemic to open-source projects involving a lot of (ex) redhat engineers. It's not that the PR is being refused, it's that it's impossible to even have the discussion.
