Sure, it just seems weird having a successful and famous developer on kickstarter. It'd be like Will Wright and Maxis having a kickstarter campaign or Sid Meier and Firaxis. I just think kickstarter should be reserved for smaller developers that don't really have other options for funding -- not famous and successful developers with industry contacts coming out their ass. Not that I think there's anything wrong with this campaign per se, it just feels weird and a bit icky to me.
Most developers are only one failed game away from bankruptcy, and they also rely completely on publishers for funding, very few have the luxury to fund their own games. Most often they will have to get whatever projects they can get to stay afloat.
kickstarter is for everyone that people want to pay for up front, it's not exclusive for the indie scene in any way, but a side-effect is usually that the projects on kickstarter end up being independant, much like this project from doublefine will be.
On the subject, if firaxis put up a project in kickstarter that said "we are going to make alpha centauri 2, the funding will go towards development and buying the license. No publisher will be involved." then I would chip in without a single moments doubt, since not only would I get the game, I would actually get a game that just wouldn't happen at all.
