Twitter Sides With Tesla's Elon Musk In Failed Apple Deal: Make Tim Cook ‘Regret It’ 12/23/20 AT 12:13 PM A spat between two of the most prominent U.S. tech leaders has generated strong interest on social media. Some Twitter users defended the CEO of Tesla (TSLA), Elon Musk, over a tweet that referenced a meeting that never happened with Tim Cook, the CEO of Apple (AAPL). According to Musk, there was a time when he considered selling Tesla to Apple for a tenth of its value, but Cook refused to meet with him over the deal. Cook, who has been Apple's chief executive since 2011, has not responded to Musk's comments.
