It is also an example of the stuff that these particular unpaid volunteers, working on their own project for fun for years on end, wanted to write.
Open source projects are not always about marketing, adoption and being friendly to everyone. Heck, this particular project didn't even have a stable release for over 10 years...
Obviously as unpaid volunteers they're not obligated on any level to be polite, neutral, and professional. But that's not the whole point.
There are two ways to deviate from a neutral, professional presentation. You can be snarky, mean, or just plain evil (negative), or you can be silly, colorful, and nice (positive). Each of them breeds more emotions of the same kind - excepting those who would wish for a professional presentation, regardless. I want to live in a world where everyone would wish only to breed positive emotions, or none at all.
