Therefore, the purpose of this Regulation is to contribute to the proper functioning of the internal market by laying down rules to ensure contestability and fairness for the markets in the digital sector in general, and for business users and end users of core platform services provided by gatekeepers in particular. Business users and end users of core platform services provided by gatekeepers should be afforded appropriate regulatory safeguards throughout the Union against the unfair practices of gatekeepers, in order to facilitate cross-border business within the Union and thereby improve the proper functioning of the internal market, and to eliminate existing or likely emerging fragmentation in the specific areas covered by this Regulation. Moreover, while gatekeepers tend to adopt global or at least pan-European business models and algorithmic structures, they can adopt, and in some cases have adopted, different business conditions and practices in different Member States, which is liable to create disparities between the competitive conditions for the users of core platform services provided by gatekeepers, to the detriment of integration of the internal market.
