• SpaceX CEO Elon Musk tweeted on Friday that he had never seen the SpaceX Facebook page and planned to delete it.
  • He's the latest tech entreprenur to discuss Facebook in the wake of the Cambridge Analytica scandal which has cut tens of billions of dollars off of Facebook's market value.

Tesla and SpaceX have apparently deleted their Facebook pages, after Elon Musk -- the CEO of both companies -- seemed to join the #DeleteFacebook movement.

It started when Musk replied to a tweet from earlier in the week from WhatsApp cofounder Brian Acton, where he tweeted "It is time. #deletefacebook." Facebook bought WhatsApp for $19 billion in 2014, making Acton a billionaire.

On Friday morning, Musk answered Acton's tweet with "What's Facebook?"

"Delete SpaceX page on Facebook if you're the man?" a fan chimed in.

"I didn't realize there was one. Will do," Musk replied.

In subsequent tweets, Musk reiterated that the SpaceX page "will be gone soon" and that he "literally never seen it even once." He also said that Facebook's influence had started to affect Instagram, the social network's photo-sharing app.

Less than 30 minutes after that tweet, the official Facebook page for SpaceX, along with that of Tesla, vanished.

Musk's negative feelings towards Facebook may be related to a 2016 dispute where Zuckerberg blamed SpaceX for a failed launch which destroyed a Facebook satellite.

"Yeah, my fault for being an idiot. We did give them a free launch to make up for it and I think they had some insurance," Musk said in a tweet to Mashable's Kerry Flynn.

Musk is the latest notable tech entrepreneur to wade into the recent Cambridge Analytica scandal, which centers on the British data company Cambridge Analytica, which has ties to Donald Trump's 2016 presidential campaign. It improperly obtained information from as many as 50 million Facebook profiles.

The outrage forced Facebook CEO Mark Zuckerberg to make a formal apology and announce plans for new tools that help users protect their data.

SpaceX's Facebook page had 2.6 million likes before it was deleted. SpaceX still has a profile on Facebook-owned Instagram.
