Poetry and Philosophy have a lot in common when it comes to education. Both are worthy subjects and certainly broaden the mind of those who study them, but neither is an area of focus in creating the future workforce of the US. As periphery subjects, they have great value, and they are not about to go away. The author of that article is saying that CC doesn't concentrate on poetry, that's a good thing. Math, science, and ELA are the focus of CC. Seems to be yet another grasping at straws argument against CC. Archery isn't covered by CC either, yet we have a great archery in the schools program here in our PE department.
