Ask HN: Do declining/ed prog langs have more unreasonableness and rudeness?

I won't say which ecosystem, but they dismiss contributions and "other" people not in their routine clique. And if you refuse to bend over to their unprofessionalism, "You're a bad person. If you continue, I will become more self-righteous and ban you. There, I banned you." agro abruptly without saying anything. Doesn't exactly encourage participation.

Is this common amongst languages no one uses or languages that are past their prime?
