The person you're replying to already has answered this question in a post you've already replied to. But to be explicit, consider the first sentence of the follow up post [1]:

> Now that you know what right-half-plane zeros are, in this article I'm going to begin a deep-dive into a control-systems-based analysis of a certain feedback system that is drawing particular public attention today: inflation.

In my mind, this is explicitly drawing a connection between the author's engineering background, particularly in control theory, and the current topic, inflation. To be clear, it would be fine if the author wanted to make a _mathematical_ connection between control theory and inflation. However, since the author does not explain right-half-plane zeros with any meaningful technical detail, the rhetorical effect is an appeal: "just trust me on this." Then the author switches topics _and explicitly connects the two topics_. I cannot speak for the person you're replying to, but this rhetoric is what bothers me.
