>>65624638KFP doesn't like Mori and deadbeats because when Mori was at the peak of her popularity, deadbeats were also constantly shitting on Kiara and Takamori, calling Kiara a leech, etc. Even though they were just doing kayfabe, deadbeats took it seriously and tried to use Mori's bad tsundere act as proof she "totes" hated Kiara.
So then they killed the ship and Mori started to actively ignore Kiara, while getting closer to other members. At some point Mori all but admitted she didn't really care about Kiara.
THEN, when Mori's popularity started to wane, all of a sudden she was all over Kiara, praising her all the time, mentioning her all the time. Just like that, deadbeats became the biggest Takamori fans, in complete opposition to what they were before.
Now the deadbeats who are left try to gaslight people that "they've always liked Takamori". Given all that, can you really blame KFP for disliking Mori and her fans? As much as deadbeats try to change history, we still remember.
