These companies wouldn't pay dues unless they were getting value from it. And I bet most have got an employee whose job it is to follow what these organizations are doing to make sure they're still worth the huge dues.

So no. I imagine almost everything done by a group like this is with the explicit approval, if not at the request, of almost all their members. But by not having to put their name on it they get an out in case it blows up in their face.
