Yes, indeed, Rupert, it was certainly a group effort in one sense in that I am quite sure that BBC would have done nothing had you declined and they never heard anything more. Nevertheless, your refusal and your tweet were what legal types would call the “legal cause” and what philosophical types would call the “efficient cause”! So there. ;) But, on a more serious note, I think that what you did here provides an excellent example of how an individual can take a position that resonates with many others and that results in change. It’s an inspiring lesson for all of us.
