Dorsey also reiterated the company's position on balancing users' First Amendment rights with controlling harassment, something for which Twitter has long been criticized. "Twitter's always been about controls. People can follow whoever they want. And it's our job to make sure they see the most important things and the things that matter to them," Dorsey told Lauer. "There are tweets that promote violence, which is against our terms of service, so people have controls to block and people have controls to mute."
