This might be a bit tin-foil, but I really don't buy a lot of this news.
If the likes of Andy Jassy or Tim Cook were reportedly huge crack users, you could all but guarantee that there would be a VP or SVP that would be plotting a coup, and you'd bet that they'd have full shareholder approval. Musk owns most of his companies, bar Tesla, where he owns around 13-15%. Surely at this point there would be someone either internal or external that would love to own Tesla, even if just for the name?
Tesla doesn't really have much to gain by being attached to Musk. If anything, the outlandish shit he's got that company doing instead of fucking making the cars he's said for years they would make holds them back.
Take the news at face value, and it paints a picture where law enforcement will be involved already. Now, take it, knowing that Musk is a deeply troubled man that lost his family and is neck-deep in the alt-right machine alongside people that can handle it far better than him, and this "news" sounds like the kind of rumour that Musk would probably spread himself to make him seem more...edgy?
If it's true, coercing someone to take highly illegal drugs is probably a crime in the US, and probably one that would warrant the police to maybe pay these people a visit, perhaps?
