I don't believe musk pulled out w/o legal advice.
There is no lawyer in the world that would have advised him to blabber on twitter, especially like he's done in the past 24h.
only rationale is that it's a tactic to force them to open the books in court and hence reduce price.
Yet to be seen if that will happen.
Other explanation is that it's all a cover to sell TSLA - doubtful.
The unstable ploy will do more damage to TSLA. It's down 6% today alone.
