Twitter has threatened to take legal action against Threads, a new rival app from Meta that has gained tens of millions of users since its release on Wednesday.

On the same day, an attorney representing Twitter, Alex Spiro, sent a letter to Meta CEO Mark Zuckerberg accusing Threads of engaging in “systematic, willful, and unlawful misappropriation of Twitter’s trade secrets and other intellectual property.”

The letter, which was first reported by Semafor , accuses Meta of hiring dozens of former Twitter employees with the intention of creating a “copycat” platform.
