In her first tweet thread since becoming CEO of Twitter, Linda Yaccarino emphasized the company’s focus on freedom of speech, a topic which is most favored by owner Elon Musk.

Yaccarino wrote on Twitter and in a memo to employees, “Twitter is on a mission to become the world’s most accurate real-time information source and a global town square for communication. That’s not an empty promise.”

Yaccarino wrote, “To drive civilization forward people need access to an unfiltered exchange of information and open dialogue about the things that matter most to us.”

Stabilizing the ad business will be one of Yaccarino’s most immediate challenges. Numerous firms have stopped their ad campaigns on Twitter over issues about the rise of hate speech as well as offensive content.

Yaccarino wrote, “We have the opportunity to reach across aisles, create new partnerships, celebrate new voices, and build something together that can change the world. From what I can tell so far, we are built for this.”
