Elon Musk’s abrupt suspension of several journalists who cover Twitter widens a growing rift between the social media site and media organizations that have used the platform to build their audiences.

Individual reporters with The New York Times, The Washington Post, CNN, Voice of America and other news agencies saw their accounts go dark Thursday.

The suspensions continued Friday with the account of a Business Insider columnist who published a series of articles between 2018 and 2021 highlighting what she called dangerous Tesla manufacturing shortcomings.

Many advertisers abandoned Twitter over content moderation questions after Musk acquired it in October, and he now risks a rupture with media organizations, which are among the most active on the platform.

The company has not explained why the accounts were taken down. But Musk took to Twitter on Thursday night to accuse journalists of sharing private information about his whereabouts, which he described as “basically assassination coordinates.” He provided no evidence for that claim.

Business Insider’s Linette Lopez told The Associated Press that she was given no explanation for her suspension. Shortly before being suspended, she said she had posted court-related documents to Twitter that included a 2018 Musk email address. That address is not current, Lopez said, because “he changes his email every few weeks.”

On Tuesday, she posted a 2019 story about Tesla troubles, commenting, “Now, just like then, most of @elonmusk’s wounds are self inflicted.”

The same day, she cited reports that Musk was reneging on severance for laid-off Twitter employees, threatening workers who talk to the press and refusing to make rent payments. Lopez described his actions as “classic Elon-going-for-broke behavior.”

Alarm over the suspensions extended beyond media circles to the United Nations, which was reconsidering its involvement in Twitter. The move sets “a dangerous precedent at a time when journalists all over the world are facing censorship, physical threats and even worse,” U.N. spokesman Stephane Dujarric said.

The reporters’ suspensions followed Musk’s decision Wednesday to permanently ban an account that automatically tracked the flights of his private jet using publicly available data. That also led Twitter to change its rules for all users to prohibit the sharing of another person’s current location without their consent.

Several of the reporters suspended Thursday night had been writing about the new policy and Musk’s rationale for imposing it.
