Twitter's ban on "COVID-19 misinformation," which Elon Musk rescinded after taking over the platform in late October, mirrored the Biden administration's broad definition of that category in two important respects:
It disfavored perspectives that dissented from official advice, and it encompassed not just demonstrably false statements but also speech that was deemed "misleading" even when it was arguably or verifiably true. In a recent Free Press article, science writer David Zweig shows what that meant in practice, citing several striking examples of government-encouraged speech suppression gleaned from the internal communications that Musk has been disclosing to handpicked journalists.
