You did not address the author's point, however - that to do CSS, you now also need to know JS. That's a significant learning curve for people whose specialism is design, not coding.
I noticed this myself when we adopted React and I told my cofounder (a designer by education) that he could "just tweak the embedded HTML in there as he saw fit" (i.e. the JSX). I think I said something like "just scroll past all the code you don't understand until you reach something that looks like HTML". In practice I don't think he ever touched it - not because he's an idiot or easily intimidated, but simply because editing the HTML wasn't the most productive way forward for him anymore. Instead, he'd edit it live in devtools, make a screenshot and copy out the edited HTML+CSS sources and tossed it over to me. I don't think he was wrong about doing it that way.
I don't think you're wrong either, by the way - I don't think we made the wrong decision when we started writing our HTML (and later, also, our CSS) in JS. But, depending on your team composition, there's real world consequences to doing so that you're going to want to take into account.
