No one here read the article, it has nothing to do with it being green but with it being low contrast.
To be fair, he could’ve cut to the chase sooner. Since it was a UI UX article, HN readers probably aren’t aware that it’s a contrast between fonts and background, not blue vs green or green vs dark green.
After a two sentence paragraph expressing how the green/blue technical differentiation has become a social one, it then asks the question "Why is green worse than blue?" The next line: "The answer is color contrast."
What could they have realistically done to cut to the chase sooner in a meaningful way? The only real thing is ditching those two context building sentences. But it's two short sentences, providing relevant context.
Doesn't really feel like a valid criticism IMO.
