The result is that the RRS increases the complexity of the copyright and licensing landscape in academic publishing, creates legal risk and may not avoid author fees. These actions may leave authors having to choose between paying publication fees and complying with their funding agreements. Publishers of legacy subscription journals have already begun implementing strategies that ensure they can protect their revenue streams. However, cOAlition S has released no legal advice that explains why the RRS is valid and legally binding. The complexity of RRS CC BY licensing also creates legal risk for readers, who may not be able to fully rely on the reuse rights of a CC BY licence on the AAM. The complexity of copyright law and CC licensing gives many reasons to doubt the legal validity of an RRS licence grant, which creates legal risk for authors and their institutions.

Even though compliance with existing green open access (self-archiving) policies is poor at best, the RRS is likely to rely on authors to successfully execute the CC licensing of their work in the face of publisher resistance. However, proponents of the RRS overlook the significant administrative and legal burdens that the RRS places on authors and readers. The laudable stated aim of the RRS is to achieve immediate open access to research outputs, while preserving journal choice for authors. The Plan S Rights Retention Strategy (RRS) requires authors who are submitting to subscription journals to inform publishers that the author accepted manuscript (AAM) will be made available under a Creative Commons Attribution (CC BY) licence.
