Those are the ones I mean.
It's not just the "never-mind-what-it's-called" people - that's not so bad, really, plenty of people do well enough in music without knowing what stuff is called. And I don't think there's many who deliberately obscure information.
The problem is the shortcut folk, mostly people misusing terminology, in order to make quick buck. While pretending to offer short cuts and quick fixes, they actually make things
more complicated.
That serves their purposes, of course, because the more complicated something can be made to appear to be, the more bite-sized chunks of information it can be broken down into, the more a learner can be tied into an enfless series of "lessons".
It's in no one's interest to explain things simply. No one's going to make any money from a one-page book...

I obviously try not to mislead, but most of the time I'm thinking "for chrissake, with a bit more self-discipline you can do this all yourself!" I taught myself, why can't they??
