I have some issues with aesthetic decisions used in Black but the degree of head-nodding on the top answer in the SE post you linked is really disconcerting. The person basically says "well you're the boss so you should kindly remind your employees that its your way or the highway" in several different sentences.

It's pretty disturbing that people think this is how a manager behaves. Turns out there are reasons beyond aesthetics that people should apply strict code formatting practices.
