Gonna be honest - once you are talking about billions of dollars, nobody gives a shit about ethics. There’s what you contractually agreed to do, and that’s it.
Nobody gets to the point where they either have significant control over Twitter or have the money to buy Twitter by being ethical.
An ethical person would not have signed an agreement to almost definitely buy Twitter, intentionally giving up several common buyers’ rights on this sort of thing, and then spend the next month and a half trying to get out of it.
