I know you're making a joke but this is actually the professional answer also. The organization certainly shouldn't change course after they've put all the effort into Kubiak and everything we know suggests that post-interview he was their top target, with the only thing that's not official being the announcement. The only reason to do something like that would be if you really thought Bienemy (or whoever else) was head and shoulders above everyone out there including the person you've spent the last month or so courting for the position.
