Most of the dysfunction I see in open source projects that take an ambivalent attitude towards the bug fixes and urgent feature needs of long-term users seems based in pure ego. Core devs want to keep being the leading edge designers and implementers of the project and are extremely stingy about letting new or intermediate contributors to the project bring fresh perspective and excitement into big new feature implementation or refactoring.
You can make a lot of disingenuous arguments that this is to protect the style and design approach of the original core, but it’s not. It’s just ego.
Look, people are obviously free to say if they are dedicating their free time to some open source project, then they only want to work on the aspects of it they like or the aspects that might seem glamorous in a blog post or conference presentation or whatever.
Being “allowed” to take that attitude is pretty much inconsequential though. If you do that, your project is entering one of two modes: death mode where new developers realize you will only permit them to work on gruntwork and you lose any capacity to actually fix things because nobody joins your project, or North Korea mode like the linux kernel where some crazed monarch or oligarchs use intimidation and public shaming as primary code review techniques.
If you are a really smart core dev of open source, stop working on the big new features. I know it hurts your ego to let your baby into the hands of newbies. Instead, do more code review, tutorials, answers on SO, and go way out of your way to make new contributors feel like you are impressed with their skill, that you want to pair with them through meaningful PRs right away, no “good first task” grunt work ego crap.
