From an open letter to the OSTP:

We are active researchers in different fields who wish to make scholarship more equitable. We wholeheartedly applaud your recent memorandum ensuring free, immediate and equitable access to federally funded scholarship. Your leadership on this issue makes a brighter future possible, but there are significant risks if care is not taken in the implementation. Specifically, if the implementation of this policy reinforces the move towards expensive article processing charges (APCs) and “transformative agreements” (TAs) where institutions pay those charges directly, innovation will be hampered by restricting research dissemination to only individuals or institutions with large or dedicated publishing budgets. The risk is that this memorandum will improve equitable access at the cost of making participation in research less equitable, which could be devastating to research progress.

Over 600 scholars (and counting) have signed.
