Isn't it true that what chaebols fear most is a challenge to their management rights rather than a drop in stock prices?

For example, when an owner family controls a group with an overwhelming shareholding ratio, if the parent generation gifts shares to the next generation for succession, the children must bear a massive gift tax. Naturally, if they sell their shares to pay the gift tax, major shareholders have to pay nearly 50% in gift tax on the gifted portion, and since they lack immediate cash, they are afraid to sell shares for fear of weakening their control.
In the case of Chairman Lee Jae-yong, when Chairman Lee Kun-hee collapsed before the succession process was finalized, he pushed too hard to facilitate the Samsung BioLogics stock surge and the abnormal ratio merger between Cheil Industries and Samsung C&T, which ultimately led to lobbying the Park Geun-hye administration and serving prison time.
Since Samsung is Korea's representative company, it is said that even the FSS (Financial Supervisory Service) kept a close eye on them and warned them not to use such tactics. But for large corporations much smaller than Samsung, what is the standard route for handing over management rights to the next generation??
The company I am watching would also likely want to avoid challenges to their management rights, as their shareholding ratio would be cut in half once the parents transfer shares to the children and they pay the taxes. It's not as if the children currently hold high stakes or have much cash on hand.
