I will say this: Elon apparently is a PITA to work for. He runs his companies like he thinks they are integral to changing the world, and he expects his employees to do the same. I've heard enough anecdotes from both Tesla and SpaceX employees and former employees to buy there's some truth to the 3AM mandatory meetings, all hands on deck for crazy hours to solve something, and do it or GTFO moments. And FWIW both Tesla and SpaceX have revolutionized their markets. Even if you don't think EV's are ready to replace all ICE vehicles, you gotta admit that Tesla has changed what an EV can be. And SpaceX routinely lands and reuses orbital rockets.
Compare and contrast that with the Project Veritas video of a Twitter employee talking about how they work there. Four hours a week of actual work, work from home, if you don't feel like coming in you just take days or weeks off and no one cares, how you feel is the most important thing.
I understand why they're panicking, even as I laugh at them. They aren't being hyperbolic, there's every reason to believe that Elon is going to destroy their livelihood. At least I hope he is.
