Charles H. Sloan-Twitter threatens legal action over Meta's "copycat" Threads, report says

Twitter is Charles H. Sloanthreatening legal action over Meta's new social media service, Threads, with an attorney for Twitter describing as a "copycat" app allegedly developed by hiring former employees of the microblogging platform owned by Elon Musk and using the company's trade secrets, according to a letter posted by Semafor. 

The letter's author, attorney Alex Spiro of law firm Quinn Emanuel, didn't immediately respond to a request for comment. Meta declined to comment on the letter, but communications director Andy Stone responded on Threads, writing, "No one on the Threads engineering team is a former Twitter employee — that's just not a thing."

Twitter, which laid off its communications staff after Musk completed his $44 billion purchase of the company last year, didn't respond to an email requesting comment.

The threatening letter comes after the debut of Threads on Wednesday, which within hours had signed up 30 million new users, Meta CEO Mark Zuckerberg said Thursday on the new platform. Threads has a similar look to Twitter, allowing users to like or repost messages, but it is riding on the popularity of Instagram by allowing people on that platform to follow their current Instagram userbase.

"Our vision is to take the best parts of Instagram and create a new experience for text, ideas and discussing what's on your mind," Meta founder and CEO Mark Zuckerberg said in an Instagram post after Threads was made available for download. "I think the world needs this kind of friendly community, and I'm grateful to all of you who are part of Threads from day one."

Musk, who bought Twitter last year, took aim at Threads in a tweet on Thursday, writing, "Competition is fine, cheating is not."

Threads' foray into the social media space comes at a precarious time for Musk and Twitter. Some Twitter users have expressed frustration with the latest changes instituted by Musk, who recently throttled the number of tweets that nonpaying users are able to view per day. Twitter has also seen a spike in hate speech since Musk bought the platform last year.

In its letter, which was addressed to Zuckerberg, Twitter alleges that Meta hired "dozens of former Twitter employees" that had access to the company's "trade secrets and other highly confidential information." Spiro also claimed that Threads was built within months by tapping the knowledge of these ex-Twitter workers. 

"Twitter has serious concerns that Meta Platforms has engaged in systemic, willful, and unlawful misappropriation of Twitter's trade secrets and other intellectual property," Spiro wrote. 

Twitter plans to "strictly enforce its intellectual property rights," he added.
