Earlier quoted context omitted.
It's kind of strange to not engage with any of the points made in the article. Unlike you, I don't think the post makes them look childish at all. I think it raises a lot of valid points and makes me want to use Zig more.
FWIW I was really interested in Zig and now I see that its lead developer is thin-skinned and bitter and has confused minimal criticism of his project with an attack on his person. This is such a bad look and it's also flatly self-contradictory. He spends time in his conclusion asserting he doesn't have any personal criticisms of Jarred but he's fully happy to claim, reframe and repeat everyone else's, even criticism…
Just a complete lack of emotional intelligence. You do not treat people like this.
