Facebook on Wednesday said it considered charging application makers to access data at the social network. "To be clear, Facebook has never sold anyone's data," director of developer platforms and programs Konstantinos Papamiltiadis said in response to an AFP inquiry, adding, "Our APIs have always been free of charge and we have never required developers to pay for using them, either directly or by buying advertising."

The Wall Street Journal reported that internal emails indicating that Facebook mulled charging companies for access to user data were referred to in a lawsuit filed against the social network in 2015 by Six4Three, creator of a failed app called "Pikinis." The application enabled users to find Facebook pictures of people in bathing suits, taking advantage of an API feature that let apps access the data of social network users as well as their friends.
