Jillian York

In May 2014, she gave a talk with Jacob Appelbaum suggesting the safer sex and harm reduction movements could show advocates of liberty and privacy how their work can better reach mainstream audiences.

In 2013, when Wired included few women in its first batch of Wired's 101 Signals, a list of best writers and thinkers on the internet, York was among critics who noted the lack of women on the list. York thinks that women are sometimes given less recognition as technology intellectuals because they focus on topics less covered by popular tech magazines while in popular topics men can crowd out popular discourse with active self-promotion.

York's commentary and opinions include statements against censorship by corporations and social media organizations at the request of state governments. She holds the view that free speech should trump business interests York and EFF opposed the Philippines Cybercrime Prevention Act of 2012 because of provisions limiting online criticism in favor of a crowd sourced alternative, the Magna Carta for Philippine Internet Freedom which supports free expression and has less stringent limits on free expression online.

York has been called "one of the leading scholars on Internet control and censorship" and a specialist on free expression and social media in the Arab world. Her research on the role of social media in the Arab Spring has been widely cited. In June 2011, Foreign Policy named her one of the top-100 intellectuals discussing foreign policy on Twitter.

She is a regular columnist for Al Jazeera English and writes for Global Voices Online, where she is also on its board of directors as of 2011. She also co-founded Talk Morocco, which won the 2010 Deutsche Welle Best of Blogs Award for Best English-language blog.

In 2008, she joined the Berkman Center for Internet & Society, a research center at Harvard University that focuses on the study of cyberspace, where she worked on the OpenNet Initiative, a joint project whose goal is to monitor and report on internet filtering and surveillance practices by nations, and Herdict, and conducted research on distributed denial-of-service attacks. In 2011, she moved to the EFF, where she is the director of international freedom of expression.

From 2004 to 2007, York spent considerable time in Morocco. In 2006, York authored Morocco – Culture Smart!: The Essential Guide to Customs & Culture, a travel book on Morocco. In an article written in 2011, York wrote about the function of blogs and social media sites such as Facebook providing Moroccans a forum for discussions and information deprived by the mainstream Moroccan media.
