The Economist asks:
Before 1 October 2022, will Facebook announce that Mark Zuckerberg will cease to be the company's sole Chairman or CEO?
Mark Zuckerberg, as Facebook's sole Chairman and CEO, has been under pressure as the company's business practices face ever greater scrutiny (CBS News, Endgadget, Quartz). An announced leave of absence or addition of either a co-chairman or co-CEO would count.
NOTE 28 October 2021: We are aware of Facebook's name change to Meta. For the purposes of this question, consider this change in and of itself to be immaterial.
The question closed "No" with a closing date of 1 October 2022.
