According to GOG announcement and FAQ, the deal includes both GOG.com and the GOG Galaxy Platform, which Michał Kiciński secured for PLN 90.7 million (around $25.2 million), and does not involve Kiciński's own CD Projekt shares. It also appears that this is a friendly sale, as CD Projekt Red will keep its current and future games on GOG.

GOG was keen to note that nothing will change for its customers, including accounts and libraries, and that both offline installers will remain available and GOG Galaxy will remain optional.

More importantly, GOG has announced that the platform will remain focused on DRM-free, and that "DRM-free is more central than before".

We believe the games that shaped us deserve to stay alive: easy to find, buy, download, and play forever. But time is annoyingly good at erasing them. Rights get tangled, compatibility breaks, builds disappear, and a nostalgic evening often turns into a troubleshooting session. That’s the difference between “I’m playing today” (the game lives on) and “I’ll play someday” (the game dies).

As Michał put it: “GOG stands for freedom, independence, and genuine control.”

...

First of all, DRM-free is more central to GOG than ever. Your library stays yours to enjoy: same access, same offline installers, same sense of ownership. Your data stays with GOG, and GOG GALAXY remains optional.

We’ll keep our relationship with CD PROJEKT. CD PROJEKT RED games will continue to be available on GOG, and upcoming titles from the studio will also be released on the platform.
