Gundato: Bingo.
Like I keep saying, "DRM Free" is a buzz word. Most gamers don't even know what DRM is (they think something is DRM free as long as it isn't activation-model Securom, and don't realize that the disc check is also DRM). So anything with a lenient enough system can easily be argued as "DRM Free".
That being said, Gamersgate (from everything I have read) has only slightly more DRM than GoG. So if people are okay with calling GoG "DRM Free" (and honestly, I am. Even though it isn't :p), Gamersgate's core system is pretty damned close.
robobrien: How is GOG not DRM free? I'm not trying to start something i'm just curious.
All your games are tied to your account which can be taken away if someone on the GoG staff ever got a splinter. Admittedly, there is little to no chance of that ever happening without a good reason anywhere, but people still care about that.
You need to authenticate with the server when you download something (admittedly, it is done with a website, not a client).
You need to re-authenticate every time you update something (admittedly, I suspect someone could count the number of times GoG updated a game with fingers alone :p).
So it is basically the same model as Impulse (and GamersGate, evidently). Need to authenticate to download and update. Have the option to make a back-up of the game (I think Impulse also allows this, but I never tried their back-up since the client is so bad :p). And your games can be taken away at the drop of a hat.
There are minor differences, but once you start trying to figure out what those differences ARE, it becomes obvious that GoG counts as DRM. Unless, of course, the dividing line is "Do I authenticate with a cookie in my browser or a cookie in a client?", which I think makes EA's website DRM-free :p.
That being said, it is just a matter of how much someone is inconvenienced. DRM is a "naughty word". So people tend to associate things they don't like with it. But, since it is so poorly defined (seriously, it is vague as hell :p), people tend to effectively make it mean "Stuff I don't like". They'll put a more mature spin on that (many here prefer the definition "Anything that is designed to restrict my enjoyment of a game", which is basically the same thing :p), but it still boils down to it. So when a DRM model comes along that they don't mind (and that is actually called "DRM Free"), they are inclined to support it while still screaming that everything should be "100% DRM Free" and the like.
