I think most of us feel that he simplified what sugar is. Using sugar to bake in a cake or putting some in coffee, etc. is great and perfectly healthy in moderation.
However, considering not everyone is lucky enough to eat a clean diet or go farmer's markets his article comes off as pretentious even though it is technically correct. I have known quite a few people forced to shop at the dollar store for food and I don't think there are many whole foods there.
So, yes if you are lucky enough that you can cook a clean whole foods diet sugar is great and it's even better if you can control yourself.
