What nonsense. Silicon Valley employees are some of the best paid in the world and have chosen to enter into a contract in a capitalist society. Even if any are "economically trapped" (they're not) and it's not of their own volition (it is), it's been a year since Musk bought the company, plenty of time to find another job.
I don't think you understand what a "tyrant" is. Companies aren't democracies.
