A rule of thumb I have about covering big tech platforms is that generally you will not learn anything useful about a company from talking to their CEOs. Even when the CEO is candid in their responses, which they often are, the platforms they run have long ago ceased to be under their direct control. A big tech CEO these days is more like a head of state: trying to nudge a large, unruly population toward progress through legislation and speech-making, while managing the chaos that the worst of its citizens are inventing every day.
