Facebook, X, TikTok, Telegram etc. are all based outside Europe and are no longer (if ever were) secure virtual places where European citizens can stay. Privacy scandals, algorithmic manipulations, the spread of fake news, are just some of the problems... The situation has deteriorated very recently, and this is a danger to European democracies. It is time for a European social network, centred in Europe and based on our values: protection of privacy, democracy, inclusiveness, fight against disinformation and hate speech, pluralism. This would not require major technological revolutions or massive investments, and moreover the moment is favorable, since many users of large social networks are very unhappy with how they have evolved and are ready to look for alternatives.
