I don't think that's quite a fair assessment. Yes, they "just" play around here (it's a demonstration after all), use it in an ignorant way (I can't speak for them and their knowledge, so unclear if the ignorance is willful), and not for its intended purpose, but that doesn't mean that it can't serve other musical purposes either. It's the same with the Cajón, for example. Or the Roland TB-303. If everyone just used it like it was intended to, we wouldn't have Acid House.
