But if you look at the bylaws of the CA/B forum [1], they explicitly exclude discussion of "pricing policies, pricing formulas, prices or other terms of sale" as part of their mandate.
So we can't assume a position for or against revocation charges - it's just not within the scope of the guidelines. Which are non-binding and advisory anyway.
