“As Twitter moves into a new phase, we are re-evaluating how best to bring external insights into our policy and product development work. As part of this process, we have decided that the Trust and Security Council is not the best structure to do this,” said an email sent to members of this body.
The council was made up of various civil rights organizations, academics and other bodies that advocated for security and advised Twitter as it developed products, programs and rules, according to a web archive for the page.
