That is an awfully broad generalization. There appear to be plenty who generate some form of income from the service while drawing a clear line between their professional and personal lives, without being profoundly hyperbolic or outright fake, or many of the other stereotypes propagated by the media. The media doesn't talk about them very much for pretty much the same reason that the media doesn't talk about office works very much: the mainstream media is based upon sensationalism, much like the YouTube superstars are. Those who operate YouTube channels as a small business or a supplementary source of income are not going to get the attention because they are simply trying to do their job.
