Elon Musk started a move called #deletefacebook. The movement has grown after data firm Cambridge Analytica was accused of obtaining the personal information of about 50 million users. Mr. Musk had poked fun at speaker brand Sonos after it said it would suspend advertising on Facebook for one week.
His followers challenged him to have his own companies’ pages deleted, which he did within minutes. The pages had more than 2.5 million followers each before they were deactivated.
