Not banned

Thank you for the clarification Adrian.

While Musk did not suspend Stephen King, he has suspended millions of other users, Musks hypocrisy remains intact...
Musk suspended numerous accounts, including comedian Kathy Griffin and former NFL player Chris Kluwe.
On December 15, 2022, Musk banned the accounts of several high-profile journalists from major news organizations, including CNN, The New York Times, and The Washington Post.
Musk's decision to suspend accounts tracking his private jet was a pivotal moment. The account @ElonJet, which used publicly available data to track his flights, was banned on December 14, leading to the suspension of related accounts and those reporting on them.
He recently said, "60 Minutes are the biggest liars in the world!...They deserve a long prison sentence."
According to a recent transparency report, X suspended 5.3 million accounts in the first half of 2024.
