I'm trying to simply that with an ear for contradiction;
If P; the more group A lose -> if NOT P; the more group NOT A lose. For P -> L = some loss of privacy
(Okay it's late and I'm clutching at it a little, but something doesn't ring true)
It seems like a formulation of "network effect" on the surface. But if P => L it can't be the same L on the right hand side, no? For the group who are the exclusion of A, their L has to be a gain. Or they are not playing the game well/optimally,
Or, if you could, would you mind rewriting it in english, please?
