Yes, because having an incentive for some people to fund more is exactly the same as overpriced DLC for a finished product.
Providing exclusive in-game advantages or to those who pre-order is a very big-publisher thing to do, yes.
@epmode : you don't know how to forgive someone who said he was sorry, do you ? They aplogized a lot of time even in an article on Gamasutra. Also, they did not made a "change" like you suggested probably because they didn't wanted to offend the backers who backed for that reward (you didn't read the comments of they kickstarter, did you ?).
So all they could do is to apologize to people.
I did read the comments. I don't agree with their conclusion but they seem honest about it so I'll just leave it at that.
Congratulations on being funded, by the way!
