Zuckerberg addressed questions around the departure of Sheryl Sandberg, the company's operating chief. Sandberg built up Facebook's advertising business, making its 2012 initial public offering possible. The Wall Street Journal reported that she left after Meta began a review of her use of company resources for wedding planning. A Meta spokesperson told the newspaper that internal investigations of Sandberg didn't have anything to do with her choice to step down. "I don't think any of the stuff that's been reported contributed to her leaving the company," Zuckerberg said.
