Really, that's the issue. For those of us who pledged big in Kickstarter, our money is gone. That's always the (understood) risk... and up until this evening, I've never seriously regretted pledging as high as I did. Legally, I haven't a leg to stand on in terms of ever getting that money back.
Announcing the removal of a core tenet of the game (not a "nice to have" as Michael seems to be toning it) at this late stage leaves a very bitter taste in the mouth.
Morally, it is a betrayal of trust. Frontier have failed in their moral obligations. I will not soon forget this.
There hasn't even been an apology.
