Maslin says he used to have regular meetings with Sean Boyle, Twitter’s former head of sustainability, who was laid off in Musk’s mass cull of staff shortly after he took over in Aprll 2022. Maslin said Boyle discussed the platform’s work to develop ways of ensuring that trusted information was pushed to the top.
