I'm not saying you where wrong to make it public, what I am saying is that the back biting and hissy fits that seem to follow are pointless. I don't know, or care, what, if any, your motives , or any one else's are. I just feel that it illustrates why the enthusiasts show does not need trade input. If the lack of trade input means that the show dies then it does not deserve to continue as an enthusiasts show.
By trade I don't mean guys selling vinyl and CD's. A trade stall of that nature is a good thing for the show, and the visitors. What it does not need, and should not have is either overt or covert representation of manufactures. The show attitude and ethos could be spoiled by people borrowing kit to put into their system for the day on a much wider level than has so far been the case.
I suppose a case could be made for letting the second hand guys have a 'shop' at the show, but in that case it should be made OK for the forum members to arrange their own sales room for surplus kit, and that could cause a number of problems as well.
If the forum members, and others want to visit the show, then it needs to be decided if it is going to happen. If so, who is going to give up the time to negotiate with the hotel, organise the rooms etc. A time consuming exercise I would imagine. Having negotiated with the hotel, with a time limited option to confirm and pay, then the show is publisised, with a time limit to book and pay for your ticket. If by that date enough income has not been generated to pay the hotel, then the show does not happen, and any received payments are returned.
