Mark Zuckerberg has pitched Meta's Twitter copycat app, Threads, as a "friendly" refuge for public discourse online, framing it in sharp distinction to the more adversarial Twitter, which is owned by billionaire Elon Musk.

"We are definitely focusing on kindness and making this a friendly place," Meta CEO Zuckerberg said on Wednesday, shortly after the service's launch.

Maintaining that idealistic vision for Threads — which attracted more than 70 million users in its first two days — is another story.
