From the articles, she already has all the ADOR executives aligned/to agree with her. So it appears they wanted HYBE's stock to tank and also influence HYBE directors to agree to a sale. The Mr. A guy used to work for HYBE and brought over all the trade secrets to ADOR as well. Google "Hostile Takeover"
Even the "takeover" claim is stupid. HYBE owns 80%, whilst Min Hee Jin owns 18% and then 2% is for the others at ADOR. It's impossible to control a company or even leave a parent company with 20% ownership.
The claim is they're trying to get investors (who are aligned with her ideals) and force HYBE to sell their 80% to these investors.
This isn't a K drama where you can just align over 50% of the other shareholders to align with your plan. It makes no sense for those shareholders to align with her when HYBE is already in the green with revenue (now we know it wasn't even her with those plans, it was Mr A).
