A personal chronicle of three key legal privacy battles that have defined the digital age and shaped the internet as we know it. From a seasoned leader in the field of digital privacy rights. Throughout her career, Cindy Cohn has been driven by a fundamental question: Can we still have private conversations if we live our lives online? Privacy’s Defender chronicles her thirty-year battle to protect our right to digital privacy and shows just how central this right is to all our other rights, including our ability to organize and make change in the world. Shattering the hypermasculine myth that our digital reality was solely the work of a handful of charismatic tech founders, the author weaves her own personal story with the history of Crypto Wars, FBI gag orders, and the post-9/11 surveillance state. She describes how she became a seasoned leader in the early digital rights movement, as well as how this work serendipitously helped her discover her birth parents and find her life partner. Along the way, she also details the development of the Electronic Frontier Foundation, which she grew from a ragtag group of lawyers and hackers into one of the most powerful digital rights organizations in the world. Part memoir and part legal history for the general reader, the book is a compelling testament to just how hard-won the privacy rights we now enjoy as tech users are, but also how crucial these rights are in our efforts to combat authoritarianism, grow democracy, and strengthen other human rights.
