In one among his most infamous Twitter freakouts, Musk acquired into it with a cave diver who helped rescue 12 Thai boys and their soccer coach from the flooded Tham Luang cave complicated in the summertime of 2018.

The diver, Vernon Unsworth, apparently angered Musk by saying that Musk’s “submarine,” an air-filled tube that the Tesla CEO had offered to help with the rescue effort, had not been useful through the mission. In retaliation, Musk advised through Twitter that Unsworth was a pedophile. Musk finally deleted the tweet after backlash—and later apologized. Unsworth sued Musk for defamation anyway, solely to have Musk win out in court. Boo.
