To me it's quite clear they want the narrative to be about Naeun being a traitor to the group who can't promote their comeback because she's selfish. That way once they announce her departure the public will have a favorable reaction to the move. Especially when they say it'll be by "mutual consent" (code for "she was pressured to leave")
For yg they only want Naeun as an actress and not promoting a rival company group. For ist, the moment she left the company she was already a traitor and apink became a 5 member group. They are itching to get rid of any link to her forever and that will be accomplished if she leaves apink.
Honestly haven't seen an idol being destroyed this badly thanks to company politics since Sulli. There is no turning back. Naeun no longer has the backing of korean pandas and once kfans want a group member out, they get kicked out (or are sent to limbo like Chen or Sungmin).
