03 Elon Musk Mark Zuckerberg SPLIT
CNN  — 

Twitter is threatening Meta with a lawsuit after the blockbuster launch of Meta’s new Twitter rival, Threads — in perhaps the clearest sign yet that Twitter views the app as a competitive threat.

On Wednesday, an attorney representing Twitter sent Meta CEO Mark Zuckerberg a letter that accused the company of trade secret theft through the hiring of former Twitter employees.

The letter was first reported by Semafor. A person familiar with the matter confirmed the letter’s authenticity to CNN.

The letter by Alex Spiro, an outside lawyer for Twitter owner Elon Musk, alleged that Meta had engaged in “systematic, willful, and unlawful misappropriation of Twitter’s trade secrets and other intellectual property.”

In response to reports on the letter, Musk tweeted: “Competition is fine, cheating is not.”
