On Wednesday, Twitter users woke to find the automated ElonJet account—and its creator, University of Central Florida student Jack Sweeney—had been suspended from the platform along with several dozen accounts that used publicly available data to track the movements of a number of high-profile figures including several Russian oligarchs and former President Donald Trump.

“Twitter suspended all thirty of my Twitter accounts,” Sweeney wrote on Trump’s platform, Truth Social, Wednesday afternoon.

The suspensions came roughly one month after Twitter’s owner, Elon Musk, wrote a post highlighting his decision not to remove Sweeney’s account as a paragon of his commitment to free speech on the platform.

“My commitment to free speech extends even to not banning the account following my plane, even though that is a direct personal safety risk,” he wrote at the time.

Many users on the site were quick to point out the apparent reversal in policy from Musk, with the phrase “Elon’s jet” quickly becoming a trending topic on the platform Wednesday afternoon.

Daniel Uhlfelder, a former candidate for Florida attorney general and a well-known liberal commentator, summed up his feelings succinctly in his own reply to Musk’s November tweet following the suspension: “Liar.”

“So much for free speech,” Brianna Wu, a software engineer and liberal activist, wrote on the platform Wednesday. “Musk has killed @ElonJet, which was using public aircraft data. I’m overwhelmingly empathetic to doxing and taking action, but there’s no valid argument this endangers anyone.”

Newsweek has reached out to both Tesla and Twitter—which recently laid off members of its communications staff—for comment.

The ban came several days after Sweeney posted on Twitter and Truth Social about receiving leaked internal communications from the highest levels of Twitter limiting the visibility of the ElonJet account’s posts on the platform—a move Musk and critics of the former leadership have described as “shadow banning.”

In recent weeks, Musk and several conservative media figures have released scores of internal communications dating back to the 2020 presidential election and beyond called the “Twitter Files,” allegedly showing how Twitter staff rationalized decisions to limit the visibility of a number of accounts it believed were either threatening to incite violence or were sharing misinformation about the COVID-19 pandemic.

In selected leaks, Musk and figures like conservative columnist Bari Weiss, blogger Matt Taibbi, and climate change skeptic Michael Shellenberger make the case that Twitter improperly used its influence to silence conservatives on the platform, resulting in right-wing calls for the Department of Justice to launch an inquiry into the service’s former leadership.

“Twitter is both a social media company and a crime scene,” Musk wrote on December 10.

After a failed attempt to pay Sweeney off to stop posting, Musk appears to have become what he swore to fight.

Newsweek recently interviewed conservative author Michael P. Senger, who was removed from the platform for violating its COVID-19 misinformation policy and who believes he remains off of the platform for his criticism of the Chinese government. (Musk’s purchase of Twitter was backed, in part, by partners with financial ties to Beijing.)

Others have accused Musk of “shadow banning” mentions of competing platform Mastodon from Twitter, as well as content related to Ukraine after well-known journalist Julia Davis—a top critic of the Kremlin—saw engagement on her tweets about the conflict cut in half.

Musk, notably, has echoed a significant amount of Russian propaganda and has faced allegations of personally meeting with the country’s president, Vladimir Putin, before suggesting Ukraine cede some of its territory to the invading country in a widely criticized peace plan. (Musk has denied the meeting.)

Newsweek has reached out to Sweeney for comment. However, in an interview with BuzzFeed News, the 20-year-old said he had no plans to stop publishing the whereabouts of Musk’s jet, saying, “I can’t let him win now.”

“I’m pretty surprised, especially after he put out a tweet saying he wouldn’t do it,” Sweeney told BuzzFeed News. “But I guess after the last commotion over the weekend, he’s probably not too happy about all that.”
