I disagree. If the entire point of your product is that it adds a new but differentiating layer of functionality to well known products already in the marketplace this is a PHB friendly way of expressing that concept.
Not just PHBs. In a crowded space, where users essentially choose you semi-randomly, charts like that provide the user with some self-justification ("I picked them because, err, they have more features!").
And anyway these kind of slides are always a bit of a sleight of hand. Every software system has some features others don't, just because, and those are the ones cherry picked for this kind of slide. It doesn't necessarily mean they are feverishly working on additional features.
