It seems like Facebook is now using its policy of user privacy for ulterior motives. Vine is a new app developed by Twitter. It is basically a video creating app which allows Twitter users to create a short six seconds clip and share it on the Vine network.
This short clip emulates the effect which is similar to a looping GIF image. Vine also had the option to add friends from their Facebook list to its own network; up till Facebook updated its policies.
Yes, Facebook has intentionally banned the video app from collecting any user data from its database. This became even more evident when Facebook updated it developer policies some time after the ban.
According to Facebook, majority of the developers creating apps which depend on Facebook services will not get affected by the change in policies. The policies however do not allow applications to pick up user data from Facebook and not link back to it.
Vine conveniently allowed users to add Facebook friends to its network. However, according to Facebook, Vine is using Facebook data to replicate a social network without giving any value to Facebook itself. Thus, the ban occurred. Other policies also specify that if Facebook bans an application, any and every information collected by the app through Facebook must be deleted from the app’s database; unless the information is basic user data or the owner of the information has given permission for the information to be retained in the app database.
Facebook believes in giving users ultimate social security and tries to eliminate any connections which can misuse its data for their own personal benefits. Facebook allows independent app developers to create social networks on Facebook APIs, as long as all the information in that app is directly shared back to Facebook. Whether Facebook took this step to diminish the popularity of Twitter, or not, is unknown.
