Lets get real here. Zoro cut a yonko's attack in half and injured another one in the same chapter. He by no means took an L.
At the same time, some Zoro fans definitely got their head cannon debunked. Kaido sees Oden in Luffy instead of Zoro, Enma is confirmed a power up, and Killer was nerfed. By no means are these Ls for Zoro's character himself but rather the part of his fanbase who set their expectations too high and started treating Zoro as this unkillable God.
