Gnostic: ...Our records show that you backed the game before we committed to an offline mode and we're afraid Kickstarter pledges are an investment into a project, with the understanding that elements of the initial pitch may change or be removed as development progresses. ...
To the first sentence I would answer that as a backer you can withdraw your backing until the very last moment, so either you give all that you promised at any point to all backers or nothin to noone. Maybe the online mode was the online thing that kept this particular backer from withdrawing. The second sentence I don't like much either. If the creator has the right to change and remove elements at will then the outcome is completely arbitrary and the backer has no rights at all. That can't be the idea. Sure, the elements can be changed but this means that you have to compensate backers if you leave important things out. Offline mode and DRM free is kind of important, isn't it.
I agree that it is a difficult topic but the way they handle it and jump from one doubtful point (online is no DRM) to another (we offer you 50%) to another ("you were too early before we said it") is just pathethic. Can't they show some spine at all and pay those out who want that? I'm on the verge of actually developing happy feelings should their game fail.
VanishedOne: Given that you can withdraw Kickstarter pledges at any time while the funding campaign is still running on the site, the idea that you aren't owed everything that was promised to backers at any point before the end of the Kickstarter campaign is... Well, let's hope that out of all the people they've mistreated, at least one turns out to be a tenaciously minded lawyer.
My impression is that with this hilarious interpretation they are also damaging KS. KS surely doesn't want backers in fear that they are not benefitting from anything that other later backers were promised. Surely also KS doesn't like such an interpretation.
