I know you were trying to make a point, but when you said "Guppies are not good for bettas" instead of saying something like "Guppies aren't good for the majority of bettas but can still be housed with them under ____ conditions" it automatically gave off that guppies can never live with them and that isn't true. Who knows, maybe this betta is really chilled out and it could work?
In my opinion, even if it's a slim possibility that it could work, we don't know the aggressive levels or personality of this owner's fish, so we can assume that saying "no these wont do" is invalid.
