Dear AoIRists, I've been asked to develop a presentation on the future of freedom of expression in online environments, including discussion of multiple ways in which - in addition to whatever governments may be up to in different contexts and ways - the private enterprises that increasingly dominate and control much of our online spaces and infrastructures censor political speech and expression. One example passed on to me was of a well-established professional in a European country (i.e., not fitting the profile of terrorist, anarchist, or even leftist) who posted comments on his/her SNS page critical of the U.S. These comments disappeared from the page without notice or explanation. I would be very grateful for: 1) recommendations for careful studies of such events and phenomena which include reliable documentation of their occurrence? (Yes, I realize that documenting and studying such episodes would be extremely tricky and difficult.) And/or 2) well documented anecdotes or examples (e.g., as reported in a reliable newspaper of record) of such episodes? Please send these along offlist. I will, of course, more than happily credit the sources and authors of any examples and resources collected and used for the presentation (unless anonymity is requested instead). Many thanks in advance, - charles ess Professor in Media Studies Department of Media and Communication Director, Centre for Research on Media Innovations <http://www.hf.uio.no/imk/english/research/center/media-innovations/> University of Oslo P.O.
