Standing in the driveway in front of the building, waiting for a taxi to take me home, I have an awkward conversation with the company’s chief security officer, Alex Stamos, who has no idea why I’m standing there stunned. He asks me if I’ve figured out a way to stop working on Facebook’s entry into China. He knows my views on Facebook’s plans there. “You could say that, yes,” I tell him. “Congratulations!” he exclaims, and my taxi pulls up.
