Oh I do get that, it's just the rather cynical marketing (after all, what were Huckleberry Finn and Tom Sawyer), and a perception that YA is slapped on anything made to appeal to the valuable teen audience. There's also a faint whiff of American prudishness, where teens of course should be protected from the horrors of foul language and the throbbingly educational and much re-re-read sex scene on p172, the dread 'age-appropriate' material that's the bane of any US librarian. As a voracious reader in my teens, I emptied the library of practically anything and everything. In all honesty, I'm glad I read James Herbert and Stephen King rather than have to wade through Harry Potter and the Hunger Games. And I also got to digest Joyce, Hardy, and pretty much all the classics. Which is why I'm qualified to use big words inappropriately on the internet.
