Basically the community was split on the entire soft-fork followed by the Justin Sun Hostile takeover. Especially the Korean community who supported Justin Sun and voted on both the sockpuppet accounts and the regular witnesses, so none of the sides could take control. Many others also didn't want to pick a side as the evidence of the ninja-mines stake promises was very underwhelming. The ones creating the hive hardfork made a decision to also fork out everyone that voted on the sockpuppet accounts. In a way it's their chain and they can do whatever they want, it just happens to go completely against decentralization what they claim they stand for.
