Within the European Open Science Cloud, research results in the form of research data will be FAIR in few years. The question is how to release scholarly communication from subscriptions and copyright retention by publishers to match the EOSC developments. The University of Ljubljana suggests that as the first step the European organizations (EC, CESAER, EARTO, EUA, LERU, SE) negotiate with scientific publishers on behalf of the European research performing organizations and research funding organizations for a total transformation from subscription peer-reviewed journals to open access peer-reviewed journals. If adequate agreements are not concluded in a reasonable timeframe to match the EOSC developments, then subscription agreements with publishers should be discontinued and efforts intensified to solidify other outlets of fully open scholarly communication.
