I am someone who has got a foot in both of these worlds. Though, I code slowly and I can't really draw either.
IMHO, designers don't usually feel any importance of open-source projects because most of them/us are used to things that are aesthetically pleasing, and they would not want to burst their/our bubble. If they we're given a choice between free Linux (assuming Adobe Suite works on it) or OSX, they would be getting OSX because it suits to their world, they would be even paying extra if it was to cost more. Also, they want something that just works and don't really care whether they can see or edit the source, since their coding experience usually ends with HTML and CSS, hence the apathy.
I've worked with quite a broad range of websites and the less control I had over my work, the less I enjoyed it. Solution? If you're able to find a designer for your project, make him feel special by taking him as an equal member of the team and give him full control of the design side (aesthetics). More so, let him start from the scratch. Although, arguing about functionality (UI and UX), which has logic in it, should be encouraged, you don't want to offend him by saying his designs look bad, because a criticism coming from a programmer is as bad as it gets. Coder's blogs are usually coloured dark blue or green, that tells a lot. That's also the reasons why most designers hate working for Google. One hour meetings whether a line should be 1 or 2px thick? If you don't really like what he is doing, ditch him.
I disagree with some of this. I think a designer should have the skin to take some criticism, even from a programmer. When my programmer co-founder critiques me, I sometimes think, "shit, I must've really screwed up for him to mention something." And yes, I do think it results in better work as long as there is justification. I think that generally, one cannot be too precious about aesthetics unless there is a clear vision with core principles.
