From the WSJ:

Twitter’s top official for monitoring safety and content moderation said she resigned Thursday, the second time an executive with that role has departed since Elon Musk bought the social-media company in October.

Ella Irwin, Twitter’s head of trust and safety, declined to comment on the reason for her departure in an interview with The Wall Street Journal. She said she felt she had always been honest in her work. Irwin, who joined Twitter about a year ago, had publicly defended the company’s actions since Musk took over as she navigated a high-profile and often-scrutinized role handling content-moderation decisions.

Also on Thursday, Musk said Twitter employees had erred in how they handled the posting of a documentary called “What is a Woman?” that, according to promotional materials, “questions the logic behind a gender ideology movement that has taken aim at women and children.” Jeremy Boreing, the co-founder and co-CEO of the media company The Daily Wire, said in a series of tweets that Twitter had tried to suppress the movie by saying the content violated Twitter’s policy against misgendering.

“This was a mistake by many people at Twitter,” Musk tweeted in response to Boreing’s complaints. “Whether or not you agree with using someone’s preferred pronouns, not doing so is at most rude and certainly breaks no laws.” He added that he personally uses someone’s preferred pronouns.
