>>103238076A serious answer is yes, but the people who do are usually Nijisanji fans who feel like she "betrayed" the other branchmates by leaving and subsequently reuniting with Doki, their voldemort. And there's still many of the remaining Niji fans who just watch Mint too and just lampshade Doki.
Outside of Nijisanji, I can't think of too many people who'd dislike her. Maybe the /cgl/ girls who doxxed her a while back? Dunno if they're still around.
