Isn't this what you are speaking of?
This is the HCST website; the linked page is the one I would imagine you might have used, for others, go to categories and click on Campaigns - it usefully indicates there are 36 listed.
These are a compilation of internal and external campaigns, some current, some not but still informative to folk browsing for information and a flavour for the Trust's activities and interests.
I personally believe that this central resource is excellent and will only improve with time and experience on both sides, that of the publishers and the readers.
I don't see any indication or inference that the Trust has any notion to develop these 36 campaigns, some they will (their own), some they will in a supportive and interactive manner with the main campaign initiator and others they will simply support by publicising them for their members and others to be informed so they can make their own decisions. I think that if someone takes the trouble to read what they have taken the trouble to create, all of this is really quite clear. It is an excellent central resource available to anyone who can be bothered to read it.
I honestly wonder if TOM's acquaintance (from his diving) has ever looked at it to add to the opinion he gave? I really do doubt it, just as I believe many more who TOM claimed this supporter was representative of, wouldn't have either. This will change with time, the development time I keep speaking of; it is essential to all good, sustainable growth and I am confident it will be a real asset to supporter involvement, as it opens up other avenues, not just the Trust.
