Germany: Germany's Federal Cartel Office Prohibits Facebook From Combining User Data From Different Sources


In its decision of 06.02.2019 ("Decision")1, Germany's Federal Cartel Office (Bundeskartellamt) ("FCO") has imposed certain restrictions on Facebook2 in its processing of user data based on its data processing policy and has ordered the termination of its conduct3 in this respect. Pursuant to the Decision, Facebook is obliged to change the terms of service that is imposed on its users who are based in Germany. This Decision is significant since it examines Facebook's comprehensive processing of personal data in terms of both data protection and competition law aspects.

FCO's Suspicions of Facebook: Beginning of the Story

Until now, individuals have been able to use Facebook's social network if they agreed to the terms of services stipulating that Facebook can collect data outside of the Facebook website on the internet, or on the smartphone apps, and assign this data to the related Facebook user account4. In this respect, not only the data collected on the Facebook website, but also those collected on Facebook-owned websites and apps, as well as on third-party websites and smartphones, could be combined and assigned to the user's Facebook account5.

Third-party sources collect the data by using the corporate services of WhatsApp, Oculus, Masquerade, and Instagram, which are owned by Facebook, and through the use of third-party websites and apps6. If a third-party website has embedded "Facebook Business Tools," e.g. the "Like" button, "Facebook login," or analytical services, such as "Facebook Analytics," data will be transmitted to Facebook via APIs when the user calls up that third-party website for the first time7. As per Facebook's terms and conditions, even if users have blocked web tracking in their browser or device settings, this data can be combined with data from the user's Facebook account and used by Facebook. In accordance with Facebook's terms and conditions, this data can be combined with the data from the user's Facebook account and used by Facebook, even if users have blocked web tracking in their browser or device settings8. Pursuant to the FCO, these terms and conditions are neither justified under data protection principles, nor are they appropriate under competition law standards9.

Such combination of data sources and building a unique database on each individual user10 by Facebook attracted the FCO's attention. Then the FCO initiated a proceeding against Facebook Inc., USA, the Irish subsidiary of the company, and Facebook Germany GmbH, Hamburg, in March, 201611. The initial suspicion focused on Facebook's terms and conditions of use that may possibly violate data protection provisions. However, in the case in question, it found that Facebook's usage of terms and conditions could represent an abusive imposition of unfair conditions on its users12. Therefore, the FCO investigated whether Facebook has abused its possibly dominant position in the market for social networks with its specific terms of service with respect to its handling of user data13.

Without having conducted further market investigations, Andreas Mundt, President of the FCO, hinted at considering Facebook as a dominant company in a separate market for social networks, and sent a message to dominant companies through Facebook, as follows: "Dominant companies are subject to special obligations. These include the use of adequate terms of service as far as these are relevant to the market. For advertising-financed internet services, such as Facebook, user data is hugely important. For this reason, it is essential to also examine, under the aspect of abuse of market power, whether consumers are sufficiently informed about the type and extent of data collected."14.

The FCO intervened in Facebook's data gathering from a competition law perspective since the data protection boundaries set forth in the General Data Protection Regulation ("GDPR") were overstepped, also in view of Facebook's dominant position15.

Facebook's Market Position in Germany

Facebook is the platform that develops and operates various digital products, and online services and applications for smartphones (apps)16. In Germany, has been available in Germany since 2008 and, in 2018, the number of daily active users in Germany was approximately 23 million, while approximately 32 million users were classified as monthly active users17.

In determining the relevant market, the FCO has made a detailed analysis. It has examined Facebook's business model and its special characteristics as a multi-sided network market with free services18. Based on the demand-side substitutability in the market, the FCO defines the product market as a private social network market, with private users as the relevant opposite market side19. The relevant geographic market is determined to be Germany. Additionally, pursuant to the FCO's findings, Facebook has a dominant position in the German market for social networks for private users and is consequently subject to abuse control under German competition law20.

The FCO examined the user-based market share of Facebook on the relevant market that exceeds 95%21. When assessing the market share, the FCO considered the amount of time spent intensively using the network as an important indicator of the competitors' actual market position22. However, in accordance with the last amendment to the German Competition Act, the FCO's assessment of a company's market power is not only based on its market share23. The factors that determine market power are broadened, such as the access to competitively relevant data, economies of scale based on network effects, the behaviour of users who can use several different services or only one service, and the power of innovation-driven competitive pressure24. In addition to Facebook's high market share, the above-stated criteria reveal the market power of Facebook25. Furthermore, the FCO found that Facebook's position is further strengthened by direct network effects, and users' switching to another social network is difficult26.

Facebook's Abuse of its Dominant Position

By using and implementing the Facebook data policy, Facebook is enabled to collect user and device-related data from sources outside of Facebook, and to combine it with data that is collected through Facebook27. This collection and combination of data is found to be an abuse of a dominant position in the social network market, in the form of exploitative business terms by the FCO28. The FCO has not imposed a monetary fine on Facebook. In this case, it seems that the FCO has not focused on imposing fines to punish infringements, but to change the future behaviour of Facebook29. The FCO may, however, decide to impose a fine in the event of recurrent abusive behaviour, or in cases with a high potential for significant harm30.

Coexistence of Competition and Data Protection Law

In this case, the FCO closely examined the relation between the German competition law provisions and data protection principles of the GDPR that are mainly enforced by the data protection authorities31. Based on the Decision, it appears that the FCO finds indispensable to examine the conduct of dominant companies like Facebook under competition law, also in terms of their data processing procedures32. It is the FCO's view that the European data protection regulations, which are based on constitutional rights can or, considering the case-law of the German Federal Court of Justice (VBL-Gegenwert and Pechstein cases), must be taken into account when assessing whether data processing terms are appropriate under competition law33. As interpreted by the FCO, the regulations in the GDPR do not rule out the FCO's assessment on whether data processing terms infringe upon the GDPR34. Also, during the proceeding, the FCO had contact with data protection authorities, none of which considered they had exclusive competence35.

Should a dominant company like Facebook make the use of its service conditional upon users granting the company extensive permission to process their personal data36, this can be considered to be "exploitative business terms" and raise data protection concerns, as well. As per the FCO, monitoring the data processing activities of dominant companies cannot be fulfilled solely by data protection officers and, therefore, need the support of the competition authorities37.

The FCO examined whether the data policy is in line with the data protection assessments of the GDPR yet found that Facebook's extensive processing of personal data from other corporate services, as well as Facebook Business Tools, violates European data protection requirements, and is subject to the affected users' consent pursuant to data protection requirements38. It is deduced that in view of Facebook's dominant position in the market, users give consent to Facebook's terms and conditions only for the purpose of concluding the contract, which cannot be assessed as their free consent under the GDPR. Therefore, Facebook must no longer combine data in any comprehensive manner unless users give their express consent.


Pursuant to the FCO's Decision, Facebook is required to adapt and change its terms of service imposed on its users who are based in Germany and data processing conditions. Although Facebook disagrees with the FCO's Decision and intends to appeal the same in order for its users in Germany to continue to benefit from Facebook services39, the Decision has created a significant impact in both the competition and data protection law environments. This Decision is remarkable in many aspects. On the one hand, the market definition analysis of, and the criteria used for, determining Facebook's market power by the FCO is noteworthy in the Decision. On the other hand, and most importantly, the FCO, as a competition authority, finds itself competent to act against violations of data protection requirements where a dominant company is involved.
