I don’t see the reasoning in your answer (I do see its passive-aggressiveness, but chose to ignore it).

I asked “why?”; does your reply mean “because lack of manpower”, “because lack of skill” or something else entirely?

In case you are new to the FOSS world, that being “open source” doesn’t mean that something cannot be criticized or that people without the skill (or time!) to submit PRs must shut the fu*k up.
