From a new and important open letter signed by 17 Nobel laureates and more than 30 international organizations:

The exorbitant article processing charges (APC) that come hand-in-hand with the Author-Pays OA publishing model deepens the inequality between researchers from developed countries and those in lower income countries. […] In developing countries, APC associated with the publication of scientific articles could represent a large proportion of the annual grants (as much as 35-130%).

The letter, spearheaded by a group of young scientists, calls out Plan S for its friendly fire, and cites the momentum behind the UNESCO Recommendation. Among other suggestions, the letter calls for the creation of an ad hoc worldwide committee, a Global Initiative for Equitable OA Models.

This is one to watch—and join.
