The Strengthening Liaison between Data Protection, Antitrust and Consumer Law in the German and Italian Big Data-Driven Economies

Summary/Abstract: Nowadays, personal data represent a strategic asset for companies as they can significantly influence their market position. Indeed, the issues arising from the management of large amounts of data (so-called big data) are not only relevant for data protection authorities, since this practice has also induced the intervention of competition and consumer protection authorities. The digital economy has enhanced new forms of abuses of dominant position and unfair practices, which can be performed via the handling of big data. This paper starts by analysing the German antitrust authority vs Facebook decision in which the big-tech platform was sanctioned for having performed an exploitative abuse of dominant position through its data management strategy. Then, it focuses on the Italian antitrust authority vs WhatsApp decision, where WhatsApp was deemed responsible for unfair and aggressive practices aimed at extracting users’ consent for data-sharing purposes. These two remarkable cases will be compared and further discussed, outlining the need to rethink the strengthening interplay between data protection, competition and consumer law, as it will entail a closer contact of the respective authorities to ensure the sustainability of digital markets.
