I felt the author's post was less about taking credit from designers and more about appreciating how much value you add by learning the basics of the jobs which intersect your own. A good designer is expected to advertise their ability to write CSS and Javascript why shouldn't one expect and acknowledge the same from a good full-stack developer. Just as the JS-able designer may not be able to re-write GMail in Ember.js so the developer won't be able to necessarily create beauty but that doesn't mean the skills aren't important or as relevant in a resume.
