The final paragraph has the Crux of the issue imo. They admit their proposed solution of statically declaring functionality in an entity has a downside. > The main limitation is of course that entity types are locked down at compile-time and cannot be changed dynamically. ECS is used I believe mainly in highly dynamic games. His proposed alternative to statically hard code functionality in entities is great if you don't have a dynamic functionality which a lot of games dont. For games like RPGs or space exploration where you have a variety of different entities with a variety of different components you can't really hard code things. ECS is a great tool in certain situations. Not a great tool in others.
