The Digital Services Coordinator, as well as other competent authorities designated under this Regulation, play a crucial role in ensuring the effectiveness of the rights and obligations laid down in this Regulation and the achievement of its objectives. Accordingly, it is necessary to ensure that those authorities have the necessary means, including financial and human resources, to supervise all the providers of intermediary services falling within their competence, in the interest of all Union citizens. Given the variety of providers of intermediary services and their use of advanced technology in providing their services, it is also essential that the Digital Services Coordinator and the relevant competent authorities are equipped with the necessary number of staff and experts with specialised skills and advanced technical means, and that they autonomously manage financial resources to carry out their tasks. Furthermore, the level of resources should take into account the size, complexity and potential societal impact of the providers of intermediary services falling within their competence, as well as the reach of their services across the Union. This Regulation is without prejudice to the possibility for Member States to establish funding mechanisms based on a supervisory fee charged to providers of intermediary services under national law in compliance with Union law, to the extent that it is levied on providers of intermediary services having their main establishment in the Member State in question, that it is strictly limited to what is necessary and proportionate to cover the costs for the fulfilment of the tasks conferred upon the competent authorities pursuant to this Regulation, with the exclusion of the tasks conferred upon the Commission, and that adequate transparency is ensured regarding the levying and the use of such a supervisory fee.
