The message has been heard, and they apparently will "gladly offer DRM-free DVD for those who want it".
Now, if it gets delivered in less than 9 months, I'll call it a success (my only benchmark for completed Kickstarter physical rewards delivery so far...)

Good, though it's what they should of done to begin with, offer their backers a choice. We had the exact same problem with Larian in the Divinity: Original Sins Kickstarter, the only difference there was that we became aware of the situation and poked the issue until offered a solution prior to the physical versions being shipped. Supposedly Larian will be shipping the DRM-Free discs in August.

Off topic but thought i would mention this here:

It was a kickstarter adventure game that didn't get funded but was still finished (I backed it originally).

You can vote for it to come to gog if you like or you can buy it from the dev directly (currently $6)

This is 1/3 of the way towards goal with 33 days left - now would be a good time to get in if you do that kind of thing.
