I first learned to fly at Lee with Southampton UAS. I've been back in once since, on a formal visit to one of the various units there - since it hasn't for some time been welcoming visitors.
If it did welcome visitors, then it's likely I'd use the airfield several times per year. Given the lack of availability of Southampton these days for GA, then I imagine it would be a popular airfield to base aircraft at - I'd certainly seriously consider it if I lived in or near Southampton again.
However, I really don't buy the arguments of malign intent or incompetence. It strikes me that most of the reasons why GA is not routinely allowed to use Daedalus (as was) are misunderstandings about the difficulties of co-existing gliders, fixed wing GA, and the police ASU. I'd strongly recommend that everybody stops throwing mud about and just tries to talk about this with the management at LoS politely and constructively.
