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 games, just like for Epic DRM free games) you get mad...

By your definition, 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.

Again, quoting you:

"It doesn't require any form of Internet connection to install, launch, or play?

With all due respect, if the answer is "it does" to either one of those questions, then that's still a very strong form of DRM."

If an internet connection is required to install the game, BY YOUR DEFINITION, it's a form of DRM. You still need to download the install file from GOG at least once, which requires you logging in to your account, therefore there's DRM in place. You wouldn't be able to play a game you bought on GOG if you didn't have the data necessary to download it contrary to a true DRM free game.
