“The illegal behavior of these organizations and their executives cost X billions of dollars. Since arriving at X, I made it my mission to continue to build a platform where people, brands and advertisers can thrive in our unique, dynamic and safe environment,” Yaccarino wrote.

“We have proven our platform provides advertisers a way to showcase their brands and reach their target audiences safely, efficiently and effectively. That’s why I’ve worked in good faith with marketers across the globe to showcase our innovations and allay any concerns with brands whom I’ve partnered with for decades,” Yaccarino continued. “The unfortunate reality is that despite all our efforts, hundreds of meetings and research to the contrary, many companies chose to dismiss the facts. To those who broke the law, we say enough is enough.”

Musk commented on the announcement, responding to Yaccarino’s post with, “We tried peace for 2 years, now it is war.”
