In this open letter, I will explain why I intend to step down as Editor-in-Chief of the Journal of Cheminformatics, which also happens to be a Springer Nature journal. It took me two years to come to this decision, and it cannot be claimed that I did not carefully evaluate the various aspects of it. However, I have now come to the conclusion that the opportunity it gives me to implement my ambition to shape open science chemistry now conflicts with the interests of Springer Nature. I will here outline some of the things I have taken into consideration.
