Its just some kind of strong-arm tactic - they do it because they can. Like some bouncer outside a club who demands money, but is not employed by the club nor the act. Just standing in the door and demanding money, and you have to pay because you want to get in.All this splitting hairs over exactly who they strong-arm and who they don't is beside the point.
