Leroux: No, it's just badly worded, because it's not just about the download but also about the installation. GG doesn't officially allow you to install the games without using their online downloader, and that's more or less the same as online activation and quite different from downloading DRM-free installers from GOG (which you can freely use to install the game on any PC not connected to the internet).
That is the point. For regional restrictions to work, either the downloader or the game itself has to check if you are in said region. If GG would ever add this, I would bet good money that their easy exploit would vanish overnight.
Gersen: And once again region restriction doesn't have to have anything with DRM, if you do regional restriction at the gifting or download level; by only allowing to gift to / download in the same "region" you achieve exactly the same goal even if the game doesn't have DRMs.
If somebody uses a VPN to receive/download a gift nothing prevents you from starting the game using said VPN.
And the best way to avoid that is to use a system combining your game with an account tied to your proper region. Like Steam. Of course you can use a VPN
every-time to launch a game. But it is exactly that kind of inconvenience that will deter enough buyers.
And if that doesn't work, you can make a system like Steam even more restrictive. Like having to wait an hour after a region change to start a game. With proper DRM you have the tools. Without DRM you are at the mercy of the goodwill of gamers. And even a cursory glance at the classified thread will show you that this won't work.
