The Background to the development of the MOBIFREE project is the current mainstream mobile software ecosystem. This ecosystem is dominated by a small number of American technologies, which are known for collecting large amounts of data on users. They are closed-source and use proprietary data and standards, resulting user-‘lock-in’ and monopolizations of markets. Organizations in Europe are working to change this and to create a fair mobile software ecosystem that is pro-privacy and pro-openness, applying open-source principles and using open data and standards, contributing to digital sovereignty of Europeans. In MOBIFREE we bring together Europe’s leading organizations in this area to further develop Next Generation Internet (NGI) technologies to realize this. The Ambition of MOBIFREE is to support the digital sovereignty of European citizens and organizations by further developing open-source software that is human-centred and ethical, and by strengthening the ecosystem that provides these software solutions. The broader Objective of MOBIFREE is to scale up mobile software technologies in all four key areas of the mobile software ecosystem through co-creation and piloting with four key sectors of end-users, in order to improve the quality, privacy and openness of these software solutions, and create new business opportunities for the leading mobile software organizations in Europe making them. The Outcomes of MOBIFREE will include: • More freedom for European citizens and organizations, who will get access to improved human-centred and ethical mobile software solutions that build upon the outcomes of the NGI-programme. • New business and sustainability opportunities for the pro-privacy, open-source mobile software ecosystem in Europe and an expanding community of human-centred and ethical IT companies. • Europe’s top innovators in mobile software will be supported in improving, validating and implementing human-centred and ethical technologies.
