A different angle to the article - which I have yet to fully absorb - and from journalists, complete with podcast and from the summary:
Governments and security forces are becoming increasingly wise to the role of social media in organising and enhancing protest movements. As a result they are developing new ways to block, hack and track citizens tweets, Facebook and other social media tools in order to prevent unrest.

Protesters and citizen journalists the world over are able to stay one step ahead, however with the help of Open Source developed phone apps that allow them to communicate effectively without being tracked as easily. From letting friends know if you've been arrested to getting your story public, there is an app for all possible situations.
