I’m not so much worried about restrictions of the platform, it’s just for personal reasons. Misty and other Pokémon characters don’t bother me too much since they’re mostly silent (I don’t watch the anime, only the games). But when it comes to shows like Owl House, Gravity Falls, or any other cartoon about kids it just doesn’t sit right with me to age them up so dramatically to draw them naked.
How they’re presented also plays a role in it: Snow White is technically 14, but she’s drawn and acts like an adult, so I don’t really mind. I would point to Wendy from GF as someone also on this side of the line- even though she’s only a year older than Luz, she’s presented as more mature and adult. But Luz and Amity just feel too young to me.
This isn’t necessarily a hard set rule either, and I may someday change my mind— or I could always set it after the show, when the timeskip has them both at 18. But honestly doing Eda sounds just as fun, without the baggage.
