Absolutely, despite the best intentions of UX designers/researchers the PMs/POs (depending on org), directors and above get final say on business/technology/ final (re)design decisions, which is then broken down into the backlog for developers.
Proper (re)design initiatives need to born out of the intersection of "viability, (user) desirability, and feasibility."
Usability is only scratching the surface of how to quantify the impact of a redesign and the author doesn't acknowledge the convoluted nature of how design decisions actually get made in non design-led tech organizations. The best companies (i.e. FAANG) have data and are measuring the outcomes of design decisions before developers even get assigned the work.
From the author's vantage point and how they get assigned work, they are missing the forest for the trees.
