Sounds like an expanded version of the Raspberry Pi forum rules "Be good to each other"... But it doesn't say you can't use rust for whatever devilish antisocial purpose you had in mind, just abide by the rules if you contribute to IRC channels, github or official rust.org forum. So you could use rust and be as unfriendly as you want on reddit (so long as you don't harass people).
I don't particularly have a desire to use Rust or any other programming language for "devilish antisocial purposes". Neither do I want to be unfriendly to anyone on reddit or anywhere else.
I do find the Rust code of conduct distasteful. Basically it says that if you ever express an opinion that someone finds "uncomfortable" then you should apologize and/or be ostracized.
Well, how could I ever use Rust? Perhaps I might want to file a bug report? It would be impossible to know if I had overstepped someones comfort zone? My disdain of Political Correctness might be detected almost immediately.
It's the kind of thinking that got Douglas Crockford uninvited from giving a key note speech at a conference because his use of words like "promiscuous" in a technical sense made somebody feel uncomfortable. http://atom-morgan.github.io/in-defense ... -crockford
It's the kind of thinking that got James Damore fired from Google this summer: https://www.washingtonpost.com/news/mor ... 6fed795710
As a language Rust might be fine.
I find it a bit dishonest for rust-lang.org to describe Rust as a "systems programming language". As far as I can tell Rust cannot compile itself yet. You cannot build a Rust compiler using a Rust compiler. It depends on LLVM. That is to say C++.
Maybe one day.
