Do Open Access mandates limit academic freedom?

The Encyclopaedia Britannica defines academic freedom as "the freedom of teachers and students to teach, study, and pursue knowledge and research without unreasonable interference or restriction from law, institutional regulations, or public pressure. Its basic elements include the freedom of teachers to inquire into any subject that evokes their intellectual concern; to present their findings to their students, colleagues, and others; to publish their data and conclusions without control or censorship; and to teach in the manner they consider professionally appropriate."

From this point of view, Open Access mandates that allow for a mix of Open Access scenarios (namely, a mix of Green and Gold Open Access) should not limit the academic freedom of researchers.

Indeed, by allowing both roads, researchers can choose the most appropriate outlet for their works, and subsequently follow the necessary road to grant Open Access to them. Gold OA allows for the publication in OA journals and books, whereas Green OA allows for the parallel publication of the article in a subscription journal and the author manuscript (or post-print) in an institutional repository.
