> Amusingly, this post violates Zig's own code of conduct: https://ziglang.org/code-of-conduct

Not sure it does. Right there in the same link you posted:

  This document contains the rules that govern these spaces only:

  The ziglang organization on Codeberg
  #zig IRC channel on Libera.chat
  Zig project development Zulip chat

It may not violate the letter of the document, but it does seem to violate its spirit to me.
