Evan Spiegel, who has pushed the concept of ephemeral communication as Snapchat’s CEO, said he was “devastated” by the publication of his archived emails that were included in the most recent round of the Sony hack. “I felt like I was going to cry all morning, so I went on a walk and thought through a couple things,” he wrote in a memo that was sent to Snapchat employees Wednesday. “I even ran into one of my high school design teachers. She gave me a huge hug. I really needed it.”
