I disagree with you, but also with many of the answers that disagree with you.
My stance is that the reason you are allowed to get refunds is to maintain an healthy consumer ecosystem and disincentivize online scams.
I agree that it is not a morally good choice to take advantage of a obvious mistake (even if consideration of who gets damaged by this is relevant and non trivial) and in this sense I agree that there is a moral asymmetry in consumer-company relations that is not entirely morally justified.
On the other hand from a legal standpoint I believe this is how it should be.
