In what may be the clearest sign yet that Twitter sees Meta as a competitive threat, the former has threatened the latter with a lawsuit following the successful launch of Meta's new Twitter rival, Threads, reported CNN. An attorney for Twitter on Wednesday sent a letter to CEO Mark Zuckerberg accusing Meta of stealing trade secrets by employing former Twitter employees.

Semafor was the first to report on the letter. The veracity of the letter was confirmed to CNN by a source with knowledge of the situation. In a letter, Alex Spiro, an outside lawyer for Twitter owner Elon Musk, claimed that Meta had committed "systematic, willful, and unlawful misappropriation of Twitter's trade secrets and other intellectual property."
