Twitter's head of trust and safety among resignations

Elon Musk warned employees that Twitter could collapse unless they find other ways for it to make money

The exodus of employees at Twitter continues beyond last week mass layoffs.

Those workers who survived the jobs cuts are reportedly facing harsher work conditions and growing uncertainty about their ability to keep Twitter running safely.

The social network is losing high-level leaders responsible for data privacy, cybersecurity and complying with regulations.

That includes Yoel Roth, Twitter’s head of trust and safety — a previously little-known executive who became the public face of Twitter’s content moderation after Musk took over.

He had been praised by Musk for defending Twitter’s ongoing efforts to fight harmful misinformation and hate speech.

An executive confirmed Roth’s resignation to coworkers on an internal messaging board seen by The Associated Press.

Roth’s resignation is a "huge loss" for Twitter’s reliability and integrity, said his former coworker and friend Emily Horne.

"He’s worked incredibly hard under very challenging circumstances, including being personally targeted by some of the most vicious trolls who were active on the platform," said Horne, who oversaw global policy communications at Twitter until 2018. "He stayed through all of that because he believed so deeply in the work his team was doing to promote a public conversation and improve the health of that conversation."

Cybersecurity expert Alex Stamos, a former Facebook security chief, tweeted Thursday that there is a "serious risk of a breach with drastically reduced staff" that could also put Twitter at odds with a 2011 order from the Federal Trade Commission that required it to address serious data security lapses.

The FTC said in a statement Thursday that it is "tracking recent developments at Twitter with deep concern."

Twitter's ongoing exodus includes the company's chief privacy officer, Damien Kieran, and chief information security officer Lea Kissner, who tweeted Thursday that "I’ve made the hard decision to leave Twitter."

The developments were part of another whirlwind day in Musk's acquisition of the social media platform.

It began with an email to employees from Musk on Wednesday night ordering workers to stop working from home and show up in the office Thursday morning. He called his first "all-hands" meeting Thursday afternoon. Before that, many were relying on the billionaire Tesla CEO's public tweets for clues about Twitter's future.
