"Sony apparently knew it was unwisely hoarding internal communication. According to the website Gizmodo, Leah Weil, the studio’s general counsel, said in one message: “While undoubtedly there will be emails that need to be retained and/or stored electronically in a system other an email, many can be deleted, and I am informed by our IT colleagues that our current use of the email system for virtually everything is not the best way to do this.”
