X (twitter) is a signatory to the Christchurch Call set-up by Jacinda Ardern. Signatories agree among other things to suppress the dissemination of terrorism. Nobody is talking about this.

Signatories: https://www.christchurchcall.com/our-community

I checked the Christchurch Call website which clearly shows Xitter as a member of the community that agreed to:

"Take transparent, specific measures seeking to prevent the upload of terrorist and violent extremist content and to prevent its dissemination on social media and similar content-sharing services, including its immediate and permanent removal, without prejudice to law enforcement and user appeals requirements, in a manner consistent with human rights and fundamental freedoms. Cooperative measures to achieve these outcomes may include technology development, the expansion and use of shared databases of hashes and URLs, and effective notice and takedown procedures."
