Twitter banned all political advertising in 2019, reacting to growing concern about misinformation spreading on social media. The latest move appears to represent a break from that policy, which had banned ads by candidates, political parties, or elected or appointed government officials.

The 2022 figure topped the prior record of 936,000 vehicles delivered in 2021, but it was shy of the 1.4 million needed to reach the company's 50% growth target. Sales grew 40% year over year, while production climbed 47% to 1.37 million.

The company hasn’t explained to the journalists why it took down the accounts and made their profiles and past tweets disappear. But Musk took to Twitter on Thursday night to accuse journalists of sharing private information about his whereabouts that he described as “basically assassination coordinates.” He provided no evidence for that claim.

If all goes well during the three-week flight, the crew capsule will be propelled into a wide orbit around the moon and then return to Earth with a Pacific splashdown in December.

Elon Musk even changed his profile to “Twitter Complaint Hotline Operator” — with a photo of himself when he was a toddler holding a telephone. But it is almost impossible for those outside of Twitter to know what strings he is pulling or whose accounts have been suspended.

While Musk hasn’t offered specifics about how he would run the platform, his musings are prompting celebrations from some of those muzzled by Twitter, even as they alarm internet safety experts who predict a rise in harassment, hate speech and misinformation about topics like vaccines and elections.
