Not quite sure I grasp the meaning of "Strength is freedom" in the context of your reply, please feel free to elucidate
I'm an ex-Mil ATCO so I do have an idea of how many visit requests Mil Towers get.
I (IMHO) thought the most valid reason (security etc to one side) was that of money. If you and your band of merry spotters would care to pay for NATS (or indeed any other ATSU) to give you a feed on the internet, to campaign and take through all the various legal procedures a bill to allow these feeds on the internet and allow ATSP's to give you what you want then I'm certain its possible.
However there is no reason for any ATSP in the UK to undertake the work outlined above free, gratis and for nothing. Its not gonna happen unless the people who want it are willing to shoulder a lot of the work and put a large amount of wonga upfront to pay for the bits they cannot do
I say again 'Show me the money!'
