I have to point out that anyone that would have taken over a multibillion dollar company and trashed it, would be in the poor house looking at his best days in the back mirror plus they would have to deal with a truckload of lawsuits. Yet, he's still thriving. It seems that all of his business could do better if he was not leading them but they are all in positive light with their investors. Also, I'm pretty sure that Tesla and SpaceX would have died a long time ago but they are alive and kicking. Why is that?
Theranos was "thriving" until it wasn't. If by thriving you mean not in a cash crisis right today, then OK, there's only a handful of unpaid suppliers and contractors that I've heard of so far. Let's see if Elon ransoms the cybertruck tooling.
It's a shame. I'd love to own SpaceX - but I want to own a space company...not a social media company, an AI company, and potentially a car company one day.
