Elon Musk is reviving his original $54.20 takeover bid for Twitter Inc., perhaps because he doesn’t want to go through a legal process that divulges more embarrassing text messages. We don’t know exactly why Musk is carrying out this year’s most spectacular corporate U-turn, which Bloomberg News first reported on Tuesday, but the vitriol that Musk and Twitter have flung at one another is set to be hastily swept under the carpet as paperwork is signed. Twitter has confirmed it received his letter and that it intends to close the transaction. The deal, in other words, might actually happen.
