Twitter Blue sparks Twitter feud between Stephen King, Elon Musk, and Epic Games CEO.

Stephen King and Elon Musk exchanged tweets over the author's unwanted Twitter Blue subscription. Musk said he was personally funding King's subscription and also covering the costs for LeBron James and William Shatner. King suggested Musk donate his blue check to charity, and Musk replied by asking how much King had donated. Several celebrities with check marks tweeted they didn't pay for Twitter Blue, including Simone Biles and Jason Alexander.
