If true, this is unfortunate. The DSi store certainly suggests that Nintendo sees the value of quick, easy, "pick-up-and-play" games, and while many people have a variety of devices available to them (smart phones, computers, etc.) the more people need to bring multiple devices with them to get all their functionality, the less appealing adding one more device to the list of things to lug around becomes.
It's unwise to remind people your device isn't a "swiss army knife" affair, especially when some of them have, or are considering, smartphones.
