I am sure what you say is very largely, if not entirely true.
But I work in sales, working on large complex deals that may take years to land. Invariably there's many players to influence, not just the key decision maker(s). A big deal could involve 100's of people, all with different agendas and personalities. Invariably you cannot win over all of them, but you have to try to network and use your relationship building skills. You gain support through some person or other, who helps you get access to someone else. You get a partner organisation to talk to someone you can't reach. You try to marginalise people who are dead set against you. In short, you have a strategy and a clear plan, driving towards building a consensus and getting the decision to go your way.
It strikes me this situation is not at all dissimilar. We want "the industry" to be broadly positive towards City, or at the very least neutral. And yes there's lots of people who will stand in our way, but not everyone will and we need to build support and allies and win over those that can be won over. Maybe the chief sports write for the XYZ newspaper is a rag, but perhaps his boss is not. Maybe the editor is into rugby and doesn't care about football, but is most interested in advertising revenue. So what's our pitch to him, and how do we get to meet him? And what about the owner? etc etc.
Perhaps all of this is happening, but somehow, I doubt it.
