The article focuses on approval versus IRV, and the advantages it gives for approval are valid.

As you know, there are various other methods (Condorcet, STAR, 3-2-1, etc.) that keep most of approval's advantages, but sacrifice simplicity for better expressiveness. It would be as unreasonable for the advocates of such methods to try to undermine real-world campaigns for approval, as it would be for approval advocates to undermine those other methods.
