I don't see that as a counterpoint, but more of a post hoc theory. How could the eradicators detect and destroy their victims before we detected any signal at all from the victims? And why haven't the eradicators come for us yet?
Of course, this could always be explained by the distances involved and the limitations of light speed, but that would make the Dark Forest hypothesis redundant as an explanation as to why we haven't yet detected any alien civilisation(s).
