(Genuine question, not rhetorical)
he's a famous author. he's got a website, a publisher with an advertising budget, and other social media channels. his audience will follow him. he can post on facebook, his mailing list, his own website, or none of the above.
Quite a lot of his twitter presence is reactions to the decline in America and America's politics. Musk would probably prefer King's voice quietened.
