Why are these framed as being almost mutually exclusive? I don't get it. "How/why did this happen?" informs how you answer "What are we changing?" Even the following section, "Reasonable people", functions in this way with a "Why did this happen?" followed by "What are we changing?".
Just feels like this article has some internal conflict with itself in order to achieve a "don't do that, do this" type of style.
