From the draft UNESCO open science recommendations:
Considering science as a global public good, open science services should be viewed as essential research infrastructures, governed and owned by the community and funded collectively by governments, funders and institutions reflecting the diverse interests and needs of the research community and society. Member States are encouragea to promote non-commercial open science infrastructures …
The document also takes a strong stand against the APC, endorsing
diversity in scholarly communications with adherence to the principles of open, transparent and equitable access and supporting non-commercial publishing models and collaborative publishing models with no article processing charges or book processing charges.
If adopted in November, the UNESCO principles—even as recommendations—could be crucial in the fight against the closed-authorship policies of Plan S and the commercial publishers.
