>>86715714because with an anime style you cant cut corners the same way you can with a western style, or at least new western styles.
Mix that in with recent anime sucking a dick, the old shit not being played anymore for the younger generation and shows like what are on disney and cartoon networks 'we don't want to try so lets make a shit style that's easy' and the few animation gems (god i don't know a better non pun term for that) steven universe and BAM you got your push to go with a more tumblr style.
have to also say, the style itself may be to appeal to that crowd as well.
