I see it both ways. In one aspect, literally, it IS better than a cup. And if they can assure me they do frequent water changes, I don't see how it constitutes as abuse. Abuse to me is not overstocking, but a fish that lives in dirty water, gets bad food, and is left untreated if it has a disease. Even if something is less than ideal, it isn't really abuse IMO. Right now, my poor hamster is in a rubbermaid bin with a lid made out of an old screen door. That is definitely less than ideal, but I'm not ABUSING my hamster. Her environment is clean, she is provided with sufficient food and water, and she has access to exercise. See my point? I totally agree with what you are saying though, people should keep their bettas in a big enough container, and what they should be saying now is, "it's better than a half gallon"
