I think it is like with reading. I am not sure where you are from, but here in Australia (at least the schools i have been to) once you become like pre-teen reading suddenly becomes un-cool and looked down upon. If you openly admit to being a bookworm or read novels at school your peers start looking at you as nerdy or a geek and in some cases start bullying you for that. Honestly it is just immaturity that causes it, but i think that this is similar to what the author it trying to portray with Yuri and her art.
maybe its just cultural differences but i've never encountered any situation where drawing was frowned upon? if anything people are impressed with your ability. i understand otaku shunning maybe in asian countries but to stretch it to drawing? idk
