It's only not sound if you want to grow and sustain the business rather than turn it into your own personal $44 billion rage room for pointless glass smashing.
I'm a bit shocked that no-one "acquihired" twitter to make another real tech company without hitting all the barriers and filtering even an infinite blood-money funded startup will hit. They threw out the baby, but the bath water is still there, and cloudy and a bit cold.
The business is now in the red in the excess of 10B dollars because Elon put a 13B dollar loan on the company's books.
The company was running fine even after the market crash until Elon took over. It's in the red now, not because of bloated employees- but because of Elon Musk.
