From the article:
numerous actions by the editing staff lead to a breach of trust between the editing staff and the original creator (Enoshima)
These are detailed further down in the article:
there were incidents of the vertical-scrolling version of the manga being uploaded without going through the proper oversight and permissions, lack of oversight from the original creator regarding the approvals for the compiled book volumes and the special bonus goods, and frequent communication delays with the original creator, all causing the manga creator Sakaki to halt their drawing of the manga. The editorial staff also admitted to leaks regarding the franchise's media mix plans, which finally led to Enoshima terminating the licensing contract around the end of April earlier this year.
For those curious, here is the mangadex page for the series. The raws end at chapter 30.
And Askan took that personally...
I am curious what her move will be with the dress of Rayana's friend. They are seated across from Rayana, so perhaps she "trips" on the dress and spills something from the table onto Rayana? If there is anything I know about villainess tactics is that it often involves some piece of clothing getting stained.
