I lived in London for years, earlier than the author, and could be considered to be part of a counter culture. I have friends & family still part of what I'd call counter culture in London and both then and now it was always a game of cat & mouse, with alternative scenes moving and reacting to the rest of the city. The corporations definitely hold most power and alternative cultures exist where their reach fades. To find the counter culture you needed to find the hard to find and personal links to it. They're still there, just purposefully hard to find.
