The theory behind Kopi Luwak was that the civets knew which (coffee) berries were perfectly ripe, so ate them; in the process, pooping out the seeds (coffee beans).
Once humans found this out, now civets are kept in cavity and fed just coffee berries (i.e., they have no choice, just eat whatever is put in from of them). Natually, the beans that come out will be no different than average coffee beans. Yes, there's this whole "civet digestive enzymes" part, but that plays a negligible role IMHO.
