Your Machiavellian side is completely missing the point then - this is(was) a public event (as evidenced by GP's reference to 100k views on IG), thus there is no leverage.
You'd have leverage if there were a reasonable likelihood that you were the only hiring manager to have this information, but if everyone is on a level playing field, the leverage disappears.
