If it's not clear there are effectively two charity's; Tom's original appeal was under umbrella of NHS charities and completely separate to the Captain Tom charity itself which is 'raising awareness' (red flag) and I believe spent more on expenses that it did on charitable work.
It looks like the 'Captain Tom' charity paid for the rights to use Captain Tom imagery and so forth. The company it paid for the rights is / was owned by the daughter and son in law, who also happen to run the 'Captain Tom' charity. Or something.
