Putting their money where their mouth is, the EU decides to make academic publishing open source:
"utilizing existing open-source software has its own advantages and disadvantages.

New study: "We find that scientists are overwhelmingly (95%) failing to publish their #code and that there has been no significant improvement over time, but we also find evidence that code sharing can considerably improve #citations, particularly when combined with #OpenAccess publication." https://www.researchsquare.com/article/rs-3222221/v1
