I don't see people moving away from it any time soon. Saying DRM is baaaad on slashdot is kind of like making an argument against gun control at the NRA. There aren't many people that would argue that an ideal content solution includes DRM.
Content owners are, for the most part, unwilling to license content that is not DRM'd. Since that's the case, it makes sense to create a DRM product that attempts to solve most of the issues with DRM, namely that it's proprietary, non-transferrable, and dependent on the long term survival of the company handing out licenses. To that extent, I think Marlin is at least trying to do more than the other branded DRM schemes. The only problem with their plan is that it is reliant on getting a tipping point of CE manufacturers and content providers on board, and even then it's dependent on Apple or Netflix totally fumbling and losing their momentum, neither of which is going to happen.
In the long run, all of the companies that are using DRM are eventually going to suffer as a result of it. The trend is for data to become more ubiquitous, not less. Any data that is encumbered by access restrictions will be less favored than data that is unencumbered by such restrictions. In other words, a movie released through studios will be at a disadvantage when compared to a movie released independently. When distribution channels become completely open (not by plan but by natural progress) then you'll see mediums like film production becoming smaller, more targeted, and eventually DRM free.
