MIK0: I disagree. Lack of a drm-free version is always a concern on kickstarter.
It thankfully is, mostly, but unfortunately this concern can easily be ignored. To me it feels like no one should ever back a game project that doesn't provide DRM free installers both to their backers and regular customers, but my feelings are pretty damn irrelevant.
Developers and publishers try to weasel out of the promise all of the time. Backers reliably raise the question in the comments, yes, but they are often ignored. And when they're ignored, it's not as if those backers leap off the project.
Then there's the question of defining DRM, with developers releasing a Steam exclusive "DRM free" version, or – like Application Systems has recently done with Nelly Cootalot 2 – redefining clear cut wikipedia approved cases of DRM as "we don't think it's DRM".
As much as it hurts me to say, Armello isn't a particularly special case. Armello has been available for quite some time, keeping the DRM free promise in principle. But where was the outrage when e.g. Koch Media pressed Steam on the backer and consumer versions of Broken Sword 5? Well, there was enough to make Cecil hand out alternative discs, to those who explicitly asked of course.
Kickstarter and generally crowd funding still is, in my opinion, a great venue to ensure that games come out DRM free. But the price of freedom is eternal vigilance.
