Tesla CEO Elon Musk changed his Twitter name to 'Elona' after Russian President Vladimir Putin's ally and the Chechen Republic's head Ramzan Kadyrov mocked him as "effeminate". Kadyrov said, "Don't measure your strength against that of Putin's." "You'll need to pump up those muscles...to change from the gentle (effeminate) Elona into the brutal Elon you need to be," he added.
