Competition Law and Digital Markets: Adaptation of Traditional Categories or New Rules? Some Reflections Arising from the Amazon Cases Regarding the Access to Non-Public Data

The present paper is intended to analyse if alleged exclusionary abuses perpetrated by big digital platforms, with particular reference to the access to non-public data dealt with in the Amazon Marketplace case, can be assessed applying the legal standards that the Court of Justice developed around the refusal to deal and the margin squeeze practices. It also shows how the new Digital Markets Act, despite representing a step forward in the regulation of the activity of these economic operators, still leaves a few questions open, especially regarding its non-sectoral approach. Finally, the interplay between access to data and privacy rules is investigated.
