Twitter threatens Meta over its new Threads app

Twitter has threatened to sue Meta over its new Threads app, which Mark Zuckerberg has openly billed as a rival, claiming the company has violated Twitter’s "intellectual property rights".   In a letter to CEO Mark Zuckerberg, first published by the news outlet Semafor, a lawyer for Twitter said the company "has serious concerns that Meta Platforms (Meta) has engaged in systematic, willful, and unlawful misappropriation of Twitter’s trade secrets and other intellectual property".   "Twitter intends to strictly enforce its intellectual property rights and demands that Meta take immediate steps to stop using any Twitter trade secrets or other highly confidential information," Alex Spiro wrote in the letter.
