National: A Facebook Change Makes It Harder for Political Campaigns to See Your Friends | New York Times
When you log in to a politician’s Facebook app, the campaign enjoys relatively easy access to your friends on the social network. But starting next year, that automatic access will go away. That may provide users with some relief from unwanted messages. It will certainly help Facebook respond to complaints that it shares too much of its users’ information without their consent. But it also could lead to more campaigns advertising on the platform, which is good for the company’s bottom line. President Obama’s 2012 campaign used Facebook to create a list of 1 million people; users who signed into its website via Facebook used the campaign’s custom app to do so. They were then asked to authorize the campaign to access information about all of their Facebook friends. When granted, the campaign could compare those users with existing voter files in order to help better define the voters it needed to reach. Now many political campaigns have their own Facebook apps, not just pages.
