Sorry, but I'm saddened by about how far people are willing to go to dislike Musk.
As far as I am concerned, his contributions to the US, society, and the future via Tesla, SpaceX, Neuralink, etc., dwarf his various foibles.
P.S. if the pay packages were contractually obligated, then the courts would have forced him to pay them. Courts are generally pretty biased in favor of employees when they sue their employer.
P.P.S if his case has no merit, the advertisers are hardly unable to defend themselves, they are huge corporations. You don't need to feel sorry for them.
