All the examples that you gave are strictly in the morally grey area. Where they end up on the spectrum is up to you as a person and what values you consider more important than others. However, in this case, things are quite black and white. Someone pays money for food, they don't get any and then you keep the money anyway. Calling it anything other than theft is being delusional. If they did partial refunds or they only gave uber eats credit instead of money then this case would be in the same bucket as the ones you mentioned in your comment.
