Yes, like Jobs alluded to in his quote, the marketing people ("toner-heads") end up running the show by getting promoted. Then, they abuse their leadership capacity to make mis-guided calls regarding product design because they do not truly have the customers' needs at heart (e.g. no headphone jack). To take it one step further, there is plenty of marketing justification for removing that jack, given Apple's ownership of Beats.
