On Sunday, Twitter owner Elon Musk joined comedian Dave Chappelle on stage and was roundly booed. Musk responded on Twitter saying, “Technically, it was 90% cheers,” and that “It’s almost as if I’ve offended SF’s unhinged leftists … but nahhh.” Musk has said that he’s politically a centrist, but the tweet is just one recent example of how he’s adopted partisan language in a social media culture war. Musk has distributed Twitter records that are supposed to reveal biased censorship, indulged in far-right talking points about COVID-19 and unbanned white nationalist accounts. Today, a discussion with the Atlantic’s Charlie Warzel about how and why Musk is aligning himself with different factions of the right. Warzel writes the Galaxy Brain newsletter about tech, media and politics.
