I think their role is to keep balanced the discussions and cohesive the community (and I feel they did, until now, a damn good job) and only in second instance to be a filter for reasonable request or coordination with Nokia.
I don't know if they have any second goal, if they receive or not money, if they hope to be hired in Nokia (and honestly since they move their a** could be reasonable) and Im fine with that. Maybe something is not completely trasparent and there are some 'shade' I dont know about but I can't see a real reason to complain.
I feel the google ads on the ITT a way to keep the comunity completely independet from Nokia (and motivate the mainteiners): I have no idea how many people visit the ITT but I suppose the council should receive part of that money for their work.
I hope the coming sinergy with maemo.org don't change too much the balance that seem works so well: they should keep some indipendent way to make some money (google ads or maybe a Nokia sponsorship but related to something tangible and public like number or visitors, contests or whatever).
