Musk has long been critical of Facebook, removing the pages for both his companies in 2018.

Axar.az reports citing foreign media that Elon Musk took a swipe at Facebook, calling on his Twitter followers to delete it. "It's lame," he said.

The business magnate and investor replied to a tweet by actor Sacha Baron Cohen, who had earlier posted a picture of Facebook founder and CEO Mark Zuckerberg as a Roman Emperor.

Baron-Cohen has been an outspoken critic of social media platforms including Twitter, Google, and YouTube, calling them "the greatest propaganda machine in history" at the Anti Defamation League's International Leadership summit in November.
