GNU GPLv3 At the Heart of the Black Hole Image (www.tfir.io)
arnieswap quotes TFIR's report on the black hole image:
Free and Open Source software was at the heart of this image. The team used three different imaging software libraries to achieve the feat. Out of the three, two were fully open source libraries. The source code of the software is publicly available on GitHub.
Richard M Stallman, the founder of the GNU Project will be glad to see that both libraries (Sparselab and ehtim) are released under GNU GPL v3. Yes, you read it right – GNU GPL v3.

AFAIK, the v3 of GPL is partially in response to companies trying to do content distribution platforms using open source software. The content owners are very particular about having DRM, and the platforms on which that content is distributed have to provide some sort of secure boot chain that prevents unauthorized software from running on the *hardware*. Those companies comply with the open source GPL v2 license and publish their source code for others to use, but they do not allow modifications of that source code to run on their hardware. Not clear to me why a software license should extend to the hardware. https://en.wikipedia.org/wiki/...
