Convince them to leave
Zuck is flatly interested in acting freely in favor of his companies. When he apologizes for the negative consequences of his products, he is less sincere than when he decides to cut costs that are needed to avoid them. As for the depth of his strategic thinking in the great power struggle that Musk has launched, well, on that, it might be better to wait a bit longer to express a judgment. Certainly, Zuck has not invested much in the attempt to demonstrate that he possesses depth of thought.
