This volume addresses contemporary challenges, enabled by modern technology, that concern upholding freedom of speech where it conflicts with social rights, such as respect for private and family life, and with economic rights, such as the freedom to conduct business or the right to free movement. In today's networked world, technological shifts happen faster than most people even realize. Some of these shifts have made us all potentially powerful: media powerful. We used to sit in silence in front of newspapers and TV screens, and the world was explained to us by just a few sources. Today, thanks to the Internet, social media, and Web 2.0, we can not only share our own thoughts with everyone in a more self-determined way, but we can also take part in public debate and even co-shape it ourselves. Of course, the Internet is not a counter-design to the communication (power) structures of the past. Gains in communicative self-determination are threatened due to algorithmisation, platformisation, and value extraction from self-created private markets.
