We're sorry to hear that this annoncement has caused confusion, so let me try to address some misunderstandings that I've seen in the comments.
Naturally GOG.COM remains a DRM-free Store. GOG GALAXY 2.0 is an optional app, and was created to organize all of your games across multiple gaming platforms. The new store inside the app approaches this sentiment to welcome all games from all platforms, including GOG.COM.
It's worth pointing out that if you don't want to see it and stick to GOG.COM, you can opt out of it in the GOG GALAXY settings. That way only the GOG.COM store will be visible inside the app. We're constantly gathering feedback and are hoping to make the app better and better with each update!
