Contrast this to a system like Apple's iTunes which set up a market with strict rules the publishers had to follow to join. They HAD to sell songs individually. They HAD to sell them for 99 cents a track. They HAD to permit the user to burn them to CD. Etc, etc, etc. Steam does not have even one single "have to" when it comes to games publishers. It is a publishers wonderland.
If you have lightweight DRM on Steam games, you have the games publishers to thank for that, not Valve. Valve would not protect you from even the most extreme forms of DRM if a publisher wished to do it. Valve even goes so far as to spend hundreds of thousands of dollars (possibly millions but I doubt it) to have their developers create features which enable publishers to make it look like they're embracing digital distro when they're not. Case in point: the ability to download a game when its done... and then sit there and wait with it encrypted and complete on your hard drive, paid for... until physical retailers can get the game on their shelves. And users think this is a feature! It is a crippling of digital distro, which operates at light speed as opposed to the slow-as-molasses speed of physical distribution. Valve didn't have to do this. They could have said 'when you upload it to our servers, the customers who preordered it get the content available immediately', but they didn't, they followed the Golden Rule of Steam - The Publisher is ALWAYS right.
Because most people think that this time around, DRM is going to work perfectly, when actually, you have as much expectation it will work perfectly as that cheap Master Lock from the hardware store.
> DRM seems to just be a monkey-patch to try to get that marginal cost to be non-zero.
This is indeed the right way to think about it.
> If that money were spent providing a better, easier product, they'd make more than they do now with DRM.
Or there's the example with Steam, where you have better and easier combined with just a little DRM applied intelligently.
