You can read this article. The French passed a law giving them double the voting rights on shares of stock the government owns in private companies. Since France controls Renault, the auto company, which also owns the Japanese Nissan, that means that the French government controls Nissan now.
The CEO who took Nissan from a minor auto company to a major competitor, by now more than twice the size of Renault, tried to retain his control with a proxy fight. Carlos Ghosn, lost the fight a few days.
Now what have the French accomplished? Most French companies are minor players in the world because the government rules for employment resemble the rules of the old Soviet Union. Seniority, union rules and lifetime tenure; the basic rules of a negative sum anti-commerce world.
A giant incompetent government bureaucracy is trying to control a single autonomous individual. That individual is a commercial genius who can not be replicated. If he leaves Nissan, it will continue for awhile on the momentum of his genius but headed for failure in due time.
We get to watch a government try to control a free individual in the open market. Lefties can place their bets on the government, as they usually do.
