Booktube and YA

Another in-person video prefacing my Ya Addiction essay coming up in the next few weeks.
Is consumerism the real problem here? Or is it something else?
We know how much booktubers love YA, and I think that's part of the reason some of you are interested in this upcoming video because- why? Why the big craze? What's the allure?
At the same time, I'm noticing some hostility toward YA audiences, adults who enjoy it primarily, and the community itself for promoting the same image. Has the cliquey treatment of booktube to other communities tainted the respect of their favorite genre?
