According to a report by Gizmodo, Elon Musk has deleted the Facebook pages for his companies SpaceX and Tesla, in the wake of backlash against the social media company over the Cambridge Analytica scandal. Gizmodo points out that this could prove to be a tipping point for Facebook CEO Mark Zuckerberg, or perhaps a sign of things to come. SpaceX's Facebook page had over 2.6 million likes, and Tesla had over 2.4 million likes, before its billionaire founder ordered them to be taken down.
