Tesla CEO and founder of the Boring Company Elon Musk speaks at a news conference, in Chicago on Thursday, June 14. Whether it’s investors betting against his stock, reporters or analysts who ask tough questions or a union trying to organize his workers, Elon Musk has fought back, often around the clock on Twitter. But when Musk called a British diver involved in the Thailand cave rescue a pedophile to 22.3 million Twitter followers on July 15, he may have gone one tweet too far. (AP Photo/Kiichiro Sato, File)
