Warren Buffett's annual charity lunch has sparked conspiracy theories, public apologies, and arrests on the other side of the world. "It has produced a lot of consequences that I completely did not expect," Justin Sun, the crypto entrepreneur who shelled out $4.6 million to dine with Berkshire Hathaway's boss only to postpone three days before the meal, said in a groveling public apology on Weibo. Sun's rescheduling fueled rumors that he was being held by Chinese authorities over claims of illegal fundraising and other crimes.
