AI controversy, leadership shake-up, and advertiser tensions mark her exit
Linda Yaccarino has officially stepped down as CEO of X, the social media platform formerly known as Twitter, after serving for two years under Elon Musk’s leadership. Her resignation was made public on Wednesday, just a day after the platform’s AI chatbot, Grok, drew backlash for promoting antisemitic content, although there’s no official indication that the two events are directly connected.
Yaccarino, who was appointed in June 2023, was tasked with reviving X’s advertising business and stabilizing its public image. Her departure, however, comes during a pivotal transition, as X was recently absorbed by xAI, Musk’s artificial intelligence company. The merger has raised questions about the company’s future direction and Yaccarino’s role within it.
In a farewell post on X, Yaccarino expressed gratitude to Musk, saying she was “immensely grateful” for the opportunity to “protect free speech” and help transform X into the so-called “Everything App.” She added, “Now, the best is yet to come as X enters a new chapter with @xAI. I’ll be cheering you all on.”
Musk responded tersely: “Thank you for your contributions.”
Behind the Exit
According to a current X employee who spoke on condition of anonymity, Yaccarino’s resignation was not entirely unexpected. Her primary mandate—to lure back advertisers wary of Musk’s polarizing behavior—proved to be an uphill battle.
Her efforts were further complicated in November 2023 when Musk publicly blasted advertisers abandoning the platform, telling them to “go f**k yourself,” a statement that ignited long-term fallout in brand relations.
The recent integration of xAI’s Grok chatbot into the platform introduced new challenges. Just weeks after Musk criticized Grok for being too politically correct and vowed to overhaul it, the AI tool posted antisemitic tropes, prompting public outrage. xAI later stated it had removed offending posts and implemented new hate speech filters.
Internally, employees voiced concerns over the platform’s direction. One source noted a “lack of clarity” about X’s long-term strategy, making it harder to maintain relationships with partners and clients.
A Rocky Tenure
Before joining X, Yaccarino had built a solid reputation as a marketing executive at NBCUniversal. Her appointment was seen as a stabilizing move, especially after Musk’s acquisition of Twitter and subsequent overhaul of its leadership and policies.
However, her time at X was fraught with high-profile controversies. Under her leadership, the platform faced scrutiny for allowing harmful and misleading content to spread, including antisemitic posts and misinformation about global conflicts. In one instance, ads were shown next to pro-Nazi content, prompting several major brands to suspend spending.
In response, Yaccarino took aggressive steps, including suing the Global Alliance for Responsible Media (GARM), accusing it of orchestrating a boycott. The organization folded days after the lawsuit was filed.
Despite introducing brand safety tools and promoting a “freedom of speech, not freedom of reach” policy, user engagement declined. According to Similarweb, monthly traffic dropped from over 915 million active users when she took over to about 684 million as of last month.

Musk’s Overshadowing
Throughout her tenure, questions loomed about Yaccarino’s real authority. Musk, who remained deeply involved as CTO, often made spontaneous policy changes and public statements that complicated her efforts to maintain consistency in operations and communication.
“Being CEO of X was always going to be a tough job, and Yaccarino lasted longer than many expected,” said Jasmine Enberg, VP at research firm Emarketer. “She was constantly trying to manage a volatile situation from the sidelines.”
Anne Marie Malecha, CEO of crisis management firm Dezenhall Resources, added, “With Musk at the helm, she was in a very difficult position. He does whatever works for him in the moment, and that’s hard for any executive to navigate.”
What’s Next?
Yaccarino’s exit follows other senior-level departures across Musk’s companies, including Tesla. It also comes amid Musk’s escalating political involvement and a growing rift between him and former allies, including Donald Trump.
While X has rolled out features like high-profile podcasts and partnerships with Visa for peer-to-peer payments, the platform has struggled to live up to the vision of becoming a universal “everything app.”
Analysts speculate her resignation may have been part of the restructuring process as X merged with xAI. Malecha suggested, “If I were her, I wouldn’t be upset about walking away right now, especially given the direction things are heading with the platform and the AI controversies.”
As of now, Elon Musk has not addressed Yaccarino’s resignation in any company-wide communication, leaving staff and industry observers speculating about the next chapter for X—and who will be bold enough to take the reins next.
