There's probably some pyschopaths that enjoy the chaos and power vacuums.

There are a lot that don't want to be there. A lot returned out of necessity. Mostly from h1b visa stuff and avoiding being deported. Or getting a new job isn't as easy right now as some think it is. Teams are tiny so people are over worked and elon is making demands that require people to over work and do things immediately.

Then it's very strange that they created the #oneteam with blue hearts if they are so happy ?

To my understanding most people there are moreso hanging on because either they have nothing else lined up or because their H1B visa is going to be automatically revoked if they quit Twitter, which would force them out of the country with no grace period.

Reports from inside the company suggest a rather grim attitude. Musk has fired several engineers, even those directly aligned with his vision for the site, often over fairly minor errors and mistakes. There's no sense of loyalty to either the company, the product, the boss or even the vision, Musk has basically eroded all of that.

Musk has been treating the employees as completely expendable. He fired one of his last two principal engineers for daring to suggest that the reason he had less views was just because people weren't into his antics anymore. Then he forced 80 employees off of their current tasks just after the Superbowl to artificially boost his own priority in the algorithm over the weekend because Joe Biden got more views on his Superbowl tweet than Musk did.

I gave an example of someone who doesn't need an H1B visa and who has been involved in the tech scene for a long time. Someone who could likely get another job relatively easy.

People want to find doom and gloom, but the reality is that if Musk wants priorities changed, he is the boss and should be able to do so. 'Forced' is a pretty strong word given that he's paying their salaries and people should be able to switch tasks if the boss wants it.
