Therefore, in order to safeguard and improve the functioning of the internal market, a targeted set of uniform, effective and proportionate mandatory rules should be established at Union level. This Regulation provides the conditions for innovative digital services to emerge and to scale up in the internal market. The approximation of national regulatory measures at Union level concerning the requirements for providers of intermediary services is necessary to avoid and put an end to fragmentation of the internal market and to ensure legal certainty, thus reducing uncertainty for developers and fostering interoperability. By using requirements that are technology neutral, innovation should not be hampered but instead be stimulated.
