People doing open-source work often feel very tribal about their code and block ideas that are good but threaten their position in the community. Essentially same thing as office politics except it's not about money, it's about personal pride.
Fundamentally, if a tool is good and provides benefits then why not use it? You'll be met with concerns about maintainability if you just airdrop something written in Ada/SPARK, but that's fair - just as it was fair that the introduction of Rust in the linux kernel was indeed met with concerns about maintainability. It seems that those were resolved to the satisfcation of the group that decides things and the cost/benefit balance was considered net positive.

Taken from the above Github discussion regarding Go and Typescript.
Do I treat your post from an obvious throwaway account created 13 minutes ago as somehow representative of the C community or the Linux kernel community or for that matter as representative of any community at all?
Come on, please. There's a ton of things that I consider worth of critisicm in the Rust community, but make a better case.
For all we know it could be the same person behind both the GitHub post and the Hacker News throwaway you're speaking to.
