"For years, Jillian York has been at the forefront of defending freedom of expression online. Her new book unpacks how Silicon Valley corporations have gained more control over speech than the most ambitious of governments and how ill-prepared they often are to use that power in ways that are just and fair. Entertaining, deeply informative and often very personal, Jillian's journey into the world of online speech reflects on deep questions about how we should treat one another and who makes rules for societies in our digital world."
--Ethan Zuckerman, Associate Professor, UMass Amherst and co-founder Global Voices

"Jillian C. York gives us a personal, relevant, and accessible reflection on how our world has become governed by Silicon Valley. She takes us on an enjoyable journey from San Francisco to Tunis to Cairo to Berlin to trace the change from the early belief in maximizing free speech shared by the big tech platforms and we, the people, alike to the increasing policies of surveillance and control exercised by the platforms (and encouraged by most governments) that makes the struggle for free expression a much more demanding battle. Her conclusions offer hope and guidance as to what we need to do, not just for the sake of free speech but for the freedom to shape our very identity and agency."
--Rasha Abdulla, Professor of Mass Communication at The American University in Cairo, and author of The Internet in the Arab World

"An incisive and compelling read that places Silicon Valley's platforms and policies in a global context. York knows this terrain intimately, and she takes us to the key battlegrounds that have shaped content moderation, internet governance, and the political economies of online expression."
--Kate Crawford, author of Atlas of AI

"[Silicon Values] casts a wide-enough net over relevant topics and examples to be richly informative, while still managing to be straightforward in its style. York offers a solid entry point for those who have been following ongoing issues relating to the intersection of politics and technology."
--Jesse A. Lambertson, Library Journal

"Silicon Values traces the haphazard and chaotic creation of the speech principles that now govern the platforms billions of us use to communicate every day ... York's book drags us back to the early, heady days of social media's inception."
--Laurie Clarke, New Statesman

"Personal, hands-on expertise makes for some gripping tales, penetrating insight and persuasive advocacy ... an important study of free speech under these pervasive social media platforms ... full of energy and needed insight."
--Karlin Lillington, Irish Times

"Simple, but not simplistic. In this book, the result of more than ten years of work in the field, York travels the world to pick out the most significant cases that show how the decisions made in the tiny Silicon Valley area of California play out on the ground"
--Wendy M Grossman, ZDNet

"Silicon Values is a trenchant critique of how platform censorship is enabled by surveillance capitalism ... In an area that doesn't lend itself to simple solutions, York's insights lay an important foundation for ongoing intelligent discussion of the topic."
--Prostasia Foundation

"Timely and trenchant ... York, who for many years has been international activism director at the Electronic Freedom Foundation, certainly knows her stuff. Her proposals for change, however, are clear and democratic, arguing for independent content moderation, social inclusion, and a user-powered movement against the handful of American men who currently run the show from Silicon Valley."
--New International

"Timely and trenchant ... [York's] proposals for change ... are clear and democratic."
--Vanessa Baird, New Internationalist
