I don't recall ever eating cold fruit soup, and when I have tomato soup, I like it hot.
Are you worried about the way it's marketed? Is it becoming a way for companies to make more money on smoothies/juice? I can't imagine being concerned about the method someone prefers for eating soup/smoothie/juice except from a health standpoint. Drinking vs. spooning it is not likely to make a difference there.
