Nature expressly allows preprints. You can put your Nature paper on arXiv at any point, before or after review. Authors are perfectly able to open their papers themselves. Authors also retain all copyrights. https://www.nature.com/authors/policies/license.html https://www.nature.com/authors/policies/license.html I’m no fan of big publishing, but Nature’s policy is ok in this respect, and better than eg. IEEE.
