“SÃO PAULO, Brazil — When Elon Musk reached a deal to acquire Twitter, right-wing Telegram groups in Brazil went wild. Here at last was a muscular champion of free speech. Even more, here was someone who — users rushed to confirm — wanted Carlos Bolsonaro, son of the president, to be Twitter’s managing director in Brazil.
That was, of course, not true. But I wasn’t surprised. I had been following these groups on the messaging app for weeks, to watch how misinformation was spread in real time. In Brazil, fake news seems to be something that the population at large seems to fall victim to — Telegram just offers the sort of deepest rabbit hole you can go down. So I knew — from horrible, eye-sapping experience — that for many right-wing activists, fake news has become an article of faith, a weapon of war, the surest way of muddling the public discussion.”
