Another thought....about half way through almost every project, I begin to dislike the colors, the shapes, the pattern...everything about the quilt. Thus another UFO is born. When I make myself go back and finish them to the point of quilting and binding, I fall in love again. It's amazing how different the finished quilt looks.
But, I do agree, if you just can't or choose not to finish them, find someone who will finish and donate them for you. Many will then cherish your UFO's. If you are lucky, you may see one of them on Facebook one day.
