This talk will begin with one of the core themes of the early development of agile software - that those involved in software development should take a more collaborative role, not just building software but helping to determine how software can help its users. We believe that this engagement requires greater knowledge of a user’s goals and also responsibility for the user’s welfare and our impact on the world. While the Internet has brought great benefits in communication, it’s also led to an unprecedented opportunity for mass surveillance, both by states and private corporations. We’ll discuss how defeating such surveillance requires greater security in our communication, reversing recent centralization, and attention to user experience. Since the beginning of this year, ThoughtWorks has worked on applying these principles to email. The argument of “I have nothing to hide” is flawed and we'll explain why it is our responsibility to take up this task.
