I think the idea behind the slide is to answer the question "Why would someone use your service instead of another?" I think there are several approaches you can take to answer such a question.

Maybe a solid approach is:

Take the list of features your competitors have. Subtract the features people don't want Add the features that people are looking for that no one has.

If you implement more features, you don't necessarily have to implement them poorly. Maybe you need a larger team or more time.
