https://www.gog.com/en/gog-preservation-program direct link to GOG, because the link provided in the The Verge article is goskimresource that is blocked by my browser extension uMatrix. From the original articles FAQ at GOG:
What about macOS and Linux?
The GOG Preservation Program is currently Windows-only. Our priority is to preserve as many games as possible under the Program, before expanding to other operating systems.
Sad. How about supporting Linux? This would be the right direction to preserve games, as they are no longer tied to the Windows operating system. That's why I use Steam and do not buy on GOG.
