Eh. Linus has a long history of abusive behavior towards other Linux contributors but also apparently apologized for it and started amending his ways. The Zig person I do not know by reputation, let alone in person. One post that he later chose to amend based on feedback is not enough for me to pass that kind of judgement. If anything, the fact that he updated it shows the opposite of lack of maturity. Adults can get frustrated. What they do with it is what matters.
