Most arguments against incest are arguments where the bottom line is already written since they are made by people who just don’t want to admit they are plain grossed out by it.
The most common intelligent argument I’ve seen against incest is “power imbalance!” which in the case of your news story looks like a case of the noncentral fallacy.
In principle, a society could frown upon parent-child incest but not upon incest between siblings, but that’s not what we see, so I don’t think that’s a good explanation.
