By announcing a radical and controversial Plan S, the European Union has created facts on the ground with Open Access (OA), which is to become Gold standard (pun intended) by the year 2020. I am honoured to present you, exclusively on my site, an Appeal by several European scientists protesting against Plan S, which they fear will deprive them of quality journal venues and of international collaborative opportunities, while disadvantaging scientists whose research budgets preclude paying and playing in this OA league. The appeal authors around the Sweden-based scientist Lynn Kamerlin offer instead their own suggestions how to implement Open Science.
