VDQI explains why chartjunk is bad, and if it reduces the amount of chartjunk in the world, that is good. Many maintain a soft spot for VDQI probably because it's their first a-ha moment in terms of appreciating graphic communication. Certainly there are other directions one could go but most people are not designers. Although, I don't see the same contradiction between DOET and VDQI, I'm curious what you mean about that.
