Is Facebook Getting Possessive?

Facebook (NASDAQ:FB) knows its users: it has collected data on what they like, where they go on the Internet, and which applications they use. But most importantly, Facebook knows who its users’ friends are. This is the social network’s edge, and it is working hard to ensure no one else can access its trove of personal information, which has been built into its social graph.

Companies like Google (NASDAQ:GOOG), LinkedIn (NASDAQ:LNKD), Amazon (NASDAQ:AMZN), and Twitter all have some piece of the puzzle; they have bits and pieces of this information, web search histories, credit card numbers, and resumes. Facebook does not want them to have access to its data, too.

As TechCruch reported, Facebook is now “done giving its precious social graph to competitors.” The social network wants to host all the ways people communicate, and that has set it against Apple (NASDAQ:AAPL), Google, and others.

Its privacy policy reflects this combative stance, stating that competing social networks cannot “use Facebook Platform to export user data into a competing social network without our permission.” As a follow-up, Facebook has recently blocked the iPhone “Walkie Talkie” application Voxer, Twitter’s new video-sharing app Vine, and the new social search app Wonder, created by the Russian search engine Yandex (NASDAQ:YNDX).

Initially Facebook argued that it only blocked Voxer’s access to the social graph because it “qualified as a competing messaging platform” and “wasn’t contributing much back to Facebook,” according to TechCrunch’s Josh Constine. But when Facebook stopped Twitter’s Vine from accessing its “Find Friends,” its reasoning was clear. Vine had a prominent “share to Facebook” option, but Twitter and Facebook are competitors.

While Facebook has taken a stand against competition, it may have only created other problems for itself. With the new policy, Facebook is no longer an open platform, and developers may not want to risk creating an application that depends on Facebook data when that data could be taken away at Facebook’s discretion.
