Platform X, formerly known as Twitter, has filed a lawsuit against the Center for Countering Digital Hate Crime over activity which is aimed at hindering the freedom of expression, writes The New York Times.

The corresponding lawsuit was filed in the federal court of the Northern District of California.

X Corp., the parent company of the social media, sent a letter on July 20 to the Center for Countering Digital Hate, accusing the organization of making “a series of troubling and baseless claims that appear calculated to harm Twitter generally, and its digital advertising business specifically,” and threatening to sue.

The letter cited research published by the Center for Countering Digital Hate in June examining hate speech on Twitter, which Elon Musk has renamed

The research consisted of eight papers, including one that found that Twitter had taken no action against 99 percent of the 100 Twitter Blue accounts the center reported for “tweeting hate.” The letter called the research “false, misleading or both” and said the organization had used improper methodology.

The letter added that the center was funded by Twitter’s competitors or foreign governments “in support of an ulterior agenda.”

“Elon Musk’s actions represent a brazen attempt to silence honest criticism and independent research”, the chief executive of the Center for Countering Digital Hate Imran Ahmed said.

He is also convinced that Elon Musk wanted to stem the tide of negative stories and rebuild his relationship with advertisers. In addition, he emphasized that the Center does not accept any funding from technology companies, governments, or their affiliates.

Previously, Elon Musk stated that Twitter’s cash flow remains negative due to a nearly 50% drop in advertising revenue and a heavy debt load. He noted that Twitter did not see the increase in ad revenue expected in June. But he added that July is a little more promising.
