You a correct in that VFR traffic does not need to be issued any avoiding action against such "unknown traffic" in fact it is not even called to the VFR traffic unless we have reason to believe that it is an ac that could be co-altitude. Lyneham ATC does follow the rule iaw the ANO and JSP 552 - I should know as one of the examiners. It is only IFR traffic that is offered avoiding action, thus I think your comment "you do NOT have any right to interfere with the legitmate progress of his flight." is totally out of order.
We in the military do not 'over control' - I think we are professional controllers who provide a safe and flexible service. If you would like to discuss this further I am sure we could arrange for you to visit. You never know, you might even appreciate some of the problems that we experience.
By the way I don't suppose you were flying into EGBP today were you !!!
