As someone who works at Workiva, I completely agree.

The post comes off a little more abrasive than I'd like. I think writing it as an "email" to a hypothetical new team member makes it worse.

The point is: we take our code reviews seriously and we may point out things that seem silly or nitpicky, we may question your approach, we may make many suggestions for improvement, but at the end of the day it is nothing personal. It is for the common goal of high code quality.
