It could be that people identify DRM only as its negative side-effects (causing issues to playing games, bugs/glitches/performance issues, spyware, whatever), and thus correlate the lack (or apparent absence) of these issues as meeting their standards (not having the two items in Cyberpunk is hardly going to affect the player's experience in a significant way, and that's about all it can cause).
Of course, in many cases the problems with DRM might be in the future, not in the present, but that's another topic. They feel that an extra isn't part of the main game, and honestly, it's not a terrible jump. I feel this is where the crux lies. If a company had come on GOG, and asked us "do you want this extra content removed, or subject to an online check?" What would be the right answer? Remove the content, deny the game on GOG at all, or allow this check? If the content is trivial, would it really be right to refuse the game? And after that, we might as well give the choice to those who want it (because at that point, refusing the DRM only serves to remove options). Maybe refusing the content is the more "ethical" option (after all, it has no DRM that way, and the game is basically intact)? Or the game should be refused entirely, even if they would offer a no DRM option?
I am not saying "We should have more DRM!", but I can understand the utilitarian view of defining what's core in a game and pushing to keep it on the store, I don't think it's just people having no standards. Most importantly, I think even people with a very clear definition of what's DRM might have split answers here (between refusing the game and getting only the DRM-free version without the extra content).
Well, I also said non-intrusive, so who knows how this DRM would work, really? :p Perhaps it would also have allowances for lending, donations and change of property for the license. It was more of a thought exercise, I understand fully well that such a thing doesn't exist, but i was trying to argue that the main issue with DRM are its downsides, not its objectives (at least, not necessarily, since I assume DRM is also used to assert control beyond ethical boundaries often). In practice, the only way to not have those problems is to not have DRM, which is why we are here.
Anyway, sorry for the long-winded replies, I wouldn't want to turn this into a long debate, I don't even think we disagree on most points, my posts have a bit of devil's advocate in them. Ideally, there wouldn't be a need to think about those things when on GOG, as there would be no room to wonder if something is DRM or not.
If you are wondering, I am personally okay with buying DRM-ed games, if no option is available (or if time is of the essence, like with certainly online-only or -mostly games), but for that there is already Steam, and I buy on GOG whenever is possible, I oftent buy games years after they come out anyway, if they aren't on GOG, so I usually know by then if they are coming here or not. I strongly prefer DRM-free, but it's not a matter of principle, essentially.
