Unless he thought he could be a big enough pain in the ass that Twitter folks would rather walk away from the deal and let him skate with a few million penalty while he liquidates Tesla stock with little repercussion to the share price (unfortunately for him, the market tanked in the interim and now his deal is an absolutely amazing one for Twitter shareholders so no way they let him walk away, $1B penalty isn't even an option as this was about outside interference)
