The point is no observation available to us that is used to confirm a phenomenon as being a black hole can conclusively exclude the possibility that the same phenomenon is in reality just a black star. The two appear sufficiently similar that we currently have no way of telling them apart. The reason why we prefer the black hole explanation is the physics behind the black star explanation is less well understood.
