So…

TL;DR of this whole discussion: When I point out that you said that requiring an internet connection is a form of DRM and it therefore means that GOG basically has DRM in place because it requires an internet connection (even if it’s just once to download the installer, just like for Epic DRM free games) you get mad…

By your destination, the only way to truly own a game and for it to be DRM free is to buy a physical copy and then, as I mentioned, you’re DRM free only as long as you don’t want a patched version.
