I don't think the shopping is a bad thing. As a local it's great to have another mall to choose from. I only see it as a negative to the vacationing visitor. WDW used to be a as a whole an immersive environment that took you out of the real world. DTD added to this and provided different experiences whether it be shopping at some unique Disney stores, spending the evening at what was essentially a night club theme park, or Disney Quest. DTD used to add to the overall experience whereas now it is simply a mall that is closer. To me it's no different than if they decided to build a grocery store, sure it's great and convenient, but you have to step back and say why is Disney doing it and how does it add to the vacation experience.
