Here's an excerpt:
We should keep in mind that DMP requirements impact only a small proportion of academic researchers and, furthermore, that such requirements are only one factor motivating researchers to share their data. Just as many, if not a greater number of, researchers might face expectations from journal publishers to share the data underlying their research articles. Some researchers receive funding from federal agencies that have data sharing policies but that do not require a DMP. Also, many researchers may desire to make their data available to a wide audience for personal or altruistic reasons, such as to permit others to replicate their methods and analysis, to allow others to re-purpose their data in new ways, or to increase the visibility and impact of their work.
