I found the copied post on steam explaining that just because a game is on steam it doesn't mean it's not DMR Free, because it's t the choice of the developer's if it's DMR free or not, and he uses Larian Studios' own Dragon Commander as an example of a DRM free Steam game.

Lets clear up a few misconcpetions
You are purchasing a license for the game on Steam and GOG. Do not delude yourself into thinking you 'own' the game on GOG. You don'thttps://www.gog.com/support/policies/gog_user_agreement
2.1 We give you and other GOG users the personal right (known legally as a 'licence') to use GOG.com to download and/or stream (depending on the content) and use GOG content and other GOG services. This licence is for your personal use. We can stop or suspend this licence in some situations, which are explained later on.
Do not confuse teh inability to enforce said license as implicit ownership. You don't own the games on Steam and GOG. ANd both services explicilty say they may revoke your games.
Steam has only one real DRM module. CEG. And very few games use encrypted executables on Steam. Mostly only AAA studios bother.
With respect to Steamworks this tweet sums it uphttps://twitter.com/icculus/status/471441666419990528
Steamworks is by itself not DRM. In fact you can incorporate literally every Steamworks feature possible, and make your game 100% DRM free.http://store.steampowered.com/app/243950/
Dragon COmmander has literally every possible Steamworks feature imaginable. SteamCloud, Multiplayer matchmaking, achivements, trading cards, etc. Yet the game is 100% DRM free. Steamworks isn't DRM unless the dev MAKES it that way.
If a game is not DRM free on steam, its because the devs made it that way. Nothing on steam forces devs to put DRM on their games. Steamworks can be integrated into a game, yet be a 100% drm free game.
If you don't like the DRM on steam, go yell at the developers to make it DRM free. Because ther's literally no reason why it can't be done."
