The verified Facebook pages of Tesla and SpaceX companies have been closed shortly after CEO Elon Musk promised to do so, after being challenged by a user on Twitter.
"Delete SpaceX page on Facebook if you're the man?" a user tweeted to Tesla Inc chief Musk. His response: "I didn't realize there was one. Will do."
SpaceX's Facebook page, which had more than 2.7 million followers, is no longer accessible, while the company's Facebook-owned Instagram profile is still accessible.
Musk had begun the exchange by responding to a tweet from WhatsApp co-founder Brian Acton of the #deletefacebook tag.
"What's Facebook?" Musk tweeted.
Musk's distaste for Facebook may date back to 2016 controversy, in which Facebook founder Mark Zuckerberg blamed Musk's SpaceX for a failed launch which destroyed its satellite.
