An anonymous reader writes: An article in Communications of the ACM takes a look at how Edward Snowden's revelations about government surveillance have changed privacy behaviors across the world. The results are fairly disappointing. While the news that intelligence agencies were trawling data from everyday citizens sparked an interest in privacy, it was small, and faded quickly. Even through media coverage has continued for a long time after the initial reports, public interest dropped back to earlier levels long ago. The initial interest spike was notably less than for other major news events. Privacy-enhancing behaviors experienced a small surge, but that too failed to impart any long-term momentum. The author notes that the spike in interest "following the removal of privacy-enhancing functions in Facebook, Android, and Gmail" was stronger than the reaction to the government's privacy-eroding actions.
