While I don't intend to play devil's advocate (although it's a role I often find myself in, lol), let's consider her perspective. She may indeed have committed a crime, but it appears to be a panicked reaction from someone who feared her hard work would be undermined.
Ador, as a subsidiary of Hybe, is to some extent financially reliant on them. Without Hybe's support, she wouldn't have been able to promote NewJeans as effectively. While it's true that other girl groups have debuted with a similar style to NJ's, none have achieved NJ's level of success, and none have come from major companies that could pose a threat.
Now, imagine her parent company, one of the industry's giants, adopts her formula and achieves success with it. It's understandable how she might panic; if Illit surpasses NJ in success with the same sound and aesthetic, Hybe might not see the need to invest further in NJ, who isn’t directly under them. Moreover, they could potentially sabotage NJ's promotions, given that nearly everything falls under Hybe's umbrella.
While I hesitate to invoke sexism, succeeding as a woman in this male-dominated industry is undoubtedly challenging. From her perspective, she likely desires proper recognition for her work and resents the notion that NJ's sound is credited solely to Hybe. Cause people might start to associate that style and aesthetic with Hybe and not her. This could explain her behavior; she likely feels that her work is being overshadowed and perhaps even stolen by more powerful and influential figures.
I'm not condoning her alleged actions; there are certainly better ways to handle such a situation, and she may have inadvertently harmed her own interests. However, it's understandable how someone in her position could become paranoid and seek to distance themselves from Hybe as quickly as possible to regain full control over Ador and possibly all rights related to NJ.
How this will end ? Only God knows. I just hope that this won’t negatively impact NJ or Illit who just debuted. They are the real victims in this situation!
