Elon Musk has been tweeting a lot over the past few months.
As Tesla Inc. lurched toward a Musk-imposed deadline to build 5,000 Model 3 electric sedans in a week, the chief executive lashed out against a wide group of people he came to see as his company’s detractors. Journalists, Wall Street analysts, short sellers, labor unions and even federal crash-safety investigators found themselves on the receiving end of his prolific Twitter output. He knows it needs to stop.
