What does the author consider to be a victory?
Tim Cook was elevated because he had the operational capability to grow Apple. Jobs did not consider Cook to be a product design person. But Jobs trusted Cook to find and keep people who could design products.
By any stretch of the imagination, the company's biggest victories have been in growing and holding together the vast ecosystem of HW / SW and services that continuously deliver the highest customer satisfaction ratings. The reward for that has been becoming the biggest company in the world. (Some might consider this a victory.)
If introducing new hit products is the only kind of victory that can exist, then Apple Silicon and AirPods victories also go to Cook.
