GOG transferred the right to provide you with a DRM free game, I have no doubt, GOG won't abuse their position, if I do not abuse mine.
I simply don't trust Valve, like I do GOG, only GOG gives me the offline installer, and that makes the game my legally owned copy.
Regardless of whether they recind my right to access the site, I still bought the game, and got the installer legally.
The rights GOG keep here is to protect against abuses, not to deprive legal owners of their content, if they wanted such power. they wouldn't giove you the installer.
I can still use the installer to play the game I legally bought, it's you who rely on store clients who can't

GOG gives you the license as well, not anything else.
2. USING GOG.COM AND GOG CONTENT
You have the personal right to use GOG content and services. This right can be waived by us in some situations (examples are below). 2.1 We give you and other GOG users the personal right (known legally as a 'licence') to use GOG.com to download and/or stream (depending on the content) and use GOG content and other GOG services. This licence is for your personal use. We can stop or suspend this licence in some situations, which are explained later on.
GOG games might have extra EULAs (End User Licensing Agreement) for you to accept. 2.2 When you buy or install GOG games, you might have to agree to additional contract terms with the developer/publisher of the game (e.g. they might ask you to agree to a game specific End User Licence Agreement). If there is any inconsistency or dispute between those ‘EULAs’ and this Agreement, then this Agreement wins.
As for the video content, stream or download it and watch the way you want.
