Of course, you meant the grandparent post. That means that you're saying that because witchcraft was seen as a threat to society in the Early Modern period (but _not_ the Medieval period, when the Papal Inquisition regarded witchcraft as a superstition, and referred anyone who brought them a witchcraft charge to Ye Olde Psychyatryste), and the witches were not a threat (although there were real witches -- Kieckhefer, Richard, _Magic in the Middle Ages_ (200)) -- again, because the witches (and the enormous number of innocents who were falsely killed as witches) were not a threat in the 17th Century, anything that anyone sees as a threat at the present day is similarly not a threat.
The right thing to do is to ask whether this particular possible threat is in fact a threat. I agree with your conclusion -- I think that the parent post is right, corporations are no longer the cohesive bloc that they were as late as the 1980s -- but I think you're doing it a disservice by using such a weak argument for it.
