Love Live is plagued with SJW fanarts (I've stopped counting the obese Nozomis and black Nicos), because it's an anime/idol game filled with pretty, cute teens and has *gasp*problematic content (one of the characters likes to grope the other girls' breasts, fanservice-y outfits,...) so the SJW feel guilty for enjoying it, and their answer isn't to be mature and say "well, I dislike that aspect of the source material but still enjoy it overall" but to redesign the characters to the point you can't recognize them and screech that it's better than canon.
Even as a LL! fan, I would have never guessed Kotori here lmao
