Nonsense. Apple and Microsoft are both objectively thriving under their respective current CEOs, who have both made some tough calls and been responsible for important new products, and both now have sufficient road behind them that we can believe in their ability to call shots for the long term to at least some degree. These companies are not just treading water.

I could be wrong, but I don't think anyone outside Facebook has much respect for Zuck in terms of decisionmaking for products or anything else in particular. This may look different to a Facebook employee, of course.
