The New York Times [read free]: “Now rebranded as X, the site has experienced a surge in racist, antisemitic and other hateful speech. Under Mr. Musk’s watch, millions of people have been exposed to misinformation about climate change. Foreign governments and operatives — from Russia to China to Hamas — have spread divisive propaganda with little or no interference. Mr. Musk and his team have repeatedly asserted that such concerns are overblown, sometimes pushing back aggressively against people who voice them. Yet dozens of studies from multiple organizations have shown otherwise, demonstrating on issue after issue a similar trend: an increase in harmful content on X during Mr. Musk’s tenure. The war between Israel and Hamas — the sort of major news event that once made Twitter an essential source of information and debate — has drowned all social media platforms in false and misleading information, but for Mr. Musk’s platform in particular the war has been seen as a watershed. The conflict has captured in full how much the platform has descended into the kind of site that Mr. Musk had promised advertisers he wanted to avoid on the day he officially took over.

With disinformation about the Israel-Hamas conflict flourishing so dramatically on X, it feels that it crossed a line for a lot of people where they can see — beyond just the branding change — that the old Twitter is truly gone,” Tim Chambers of Dewey Square Group, a public affairs company that tracks social media, said in an interview. “And the new X is a shadow of that former self.”
