As far as my “view” as to whether or not it was organized, obviously, all four poskim weren’t mechaven to the same nusach and coincidentally sent it to the printer at the same time, and then he decided to save paper and put all four signatures on the same sign.
Rather, rabbonim, concerned that their kehillos would believe the misleading promotional material, arranged for a public kol koreh before the devices were actually sold. I’m told that attempts were made to reach the inventor of the switch before it went public.
