Elon Musk made headlines in 2023 when he hired Linda Yaccarino to serve as CEO of the social media platform that was then known as Twitter.

However, many observers were left blindsided earlier this week when Yaccarino announced that she is quitting. 

Yaccarino calls time with X "an opportunity of a lifetime"

According to Breitbart, Yaccarino revealed her intention to step down in an X post on Wednesday, saying that her time with the company had been "an opportunity of a lifetime."

After two incredible years, I’ve decided to step down as CEO of 𝕏.

When @elonmusk and I first spoke of his vision for X, I knew it would be the opportunity of a lifetime to carry out the extraordinary mission of this company. I’m immensely grateful to him for entrusting me…

Yaccarino stressed that she is "immensely grateful" to Musk "for entrusting me with the responsibility of protecting free speech, turning the company around, and transforming X into the Everything App."

"I'm incredibly proud of the X team - the historic business turn around we have accomplished together has been nothing short of remarkable," the outgoing CEO insisted.

CEO oversaw "groundbreaking innovations like Community Notes"

Yaccarino recalled how her team "started with the critical early work necessary to prioritize the safety of our users—especially children, and to restore advertiser confidence."

What's more, she heralded "groundbreaking innovations like Community Notes, and, soon, X Money to bringing the most iconic voices and content to the platform."

"We couldn’t have achieved that without the support of our users, business partners, and the most innovative team in the world," Yaccarino wrote as she drew to a close.

She concluded by stating, "I’ll be cheering you all on as you continue to change the world. As always, I’ll see you on X."

Yaccarino successfully fought back against advertising industry coalition

Axios pointed out that under Yaccarino's leadership, X took aim at the Global Alliance for Responsible Media (GARM) by filing "a high-profile lawsuit."

It alleged that the advertising industry coalition had "abused its influence over marketers and ad agencies to discriminate unfairly against X."

Those actions were allegedly taken in response to the increased level of content freedom that X began offering after Musk purchased the platform.

Axios explained that GARM ultimately shut down following the lawsuit while the Federal Trade Commission (FTC) reportedly launched investigations into other ad groups over similar activity.
