Twitter filed a lawsuit against the Center for Countering Digital Hate. “Despite our continued progress, the Center for Countering Digital Hate (CCDH) and its backers have been actively working to assert false and misleading claims encouraging advertisers to pause investment on the platform. X is a free public service funded largely by advertisers. Through the CCDH’s scare campaign and its ongoing pressure on brands to prevent the public’s access to free expression, the CCDH is actively working to prevent public dialogue,” the company said in a blog post Monday.

“Musk and his legal team, led by attorney Alex Spiro at Quinn Emanuel, have engaged in an aggressive campaign to intimidate, bully, and silence CCDH,” the organization said in a statement released Monday. “While Elon Musk proclaims to be a ‘free speech absolutist,’ his actions against CCDH show the lengths he will go to silence those who seek to hold him to account.”
