I completely agree. Who cares if black is ugly? It's a standard which is easy to automate. Want a better standard? Make it. Until then black works.
That is what this post is advocating for, his own fork of black.
In particular I understand that there are wrong ways to complain (and possibly the author is guilty of them), but this specific blog felt over the top and emotional (something I sympathize after unrelated experiences in failing to understand how to organize an Poly/ML project) but not unfair.
