Online digital platforms have become a key in our economic life. They brought us innovative efficiency and convenience. On the other hand, they have raised a number of competition related questions. We tend to have a limited number of powerful digital platforms in each online intermediate segment of the economy for years. One of the concerns many reports have raised is the exploitative collection and processing of consumers’ data by digital platforms. Consumers provide a lot of data, in most cases unconsciously, instead of using free digital platform services and only platforms can control them. There is a considerable asymmetry of information between digital platforms and consumers. Even though this is a serious problem, is it possible for competition law to deal with this issue or better for other laws to cope with the new situation? I will discuss this issue by focusing German Facebook case and JFTC’s Guidelines (published on 17/12/2019).
