I guess some project (especially ones where work is done on a voluntary basis) have a different scale of value, that is it's more important to first have stuff work and then make it look appealing or making it usable by non-technical users. EDIT: I think in this case a more interesting question would be: why don't people with a better aesthetic taste or UX knowledge volunteer for these kind of projects?
