This company has undergone a remarkable 'privacy-transformation'; in the beginning Facebook restricted the visibility of a users’ personal information to just their friends and their ‘network’ (private space for communication with a specific and individually selected group), but soon it transformed into a platform where much of your private information is public by default. Facebook has also changed the classification of its personal information several times, which was very confusing for their users.
To illustrate ‘Facebook’s shift away from privacy’, I have highlighted Facebook’s privacy policies in 2005, 2007 and 2010:
Privacy Facebook in 2005
The personal information that users submit to Facebook will only be available to their ‘friends’ and personal ‘network’, which can be monitored in their own privacy settings.

Privacy Facebook in 2007
The profile information which users submit to Facebook will be available to users of Facebook who belong to ‘at least one’ of the networks you allow to access your personal information through your privacy settings (for example; school, geography, friends of friends etc.). Furthermore, also your name, school name and profile picture thumbnail will be available in search results across the general network of Facebook.

Privacy Facebook in 2010
When users connect with an application or website it will have access to their ‘general’ information which includes their name, friends’ names, profile pictures, gender, user IDs, connection, and any content shared using the “everyone privacy setting” (the default privacy setting for certain types of information users post on Facebook is set to “everyone”). When users are uncomfortable with the connection being publicly available, they should consider removing (or not making) the connection.

In conclusion, this ‘privacy-transformation’ of Facebook shows a clear evolution. Facebook originally earned its core base by offering users simple and powerful controls over their personal information. As Facebook grew larger and became more important, it could have chosen to maintain or improve those controls. Instead, it slowly but surely helped itself (and its advertising and business partners) to more and more release its users' private information and limiting the users' options to control their own information...
