by Kif Leswing – business insider — The Tesla and SpaceX Facebook pages have vanished, minutes after Elon Musk — the CEO of both companies — said that he had never seen the SpaceX Facebook profile and planned to delete it. It started when Musk replied to a tweet earlier in the week from WhatsApp cofounder Brian Acton, when 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 by saying “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 toward Facebook may be related to a 2016 dispute where Zuckerberg blamed SpaceX for a failed launch that destroyed a Facebook satellite. Musk actually addressed that in a later tweet on Friday, taking the blame for the accident. “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.
