That clause is the exact reason many of us saw the old patent terms as being offensive rather than defensive. Why would it be valuable to Facebook to prevent people from arguing that their patents are invalid, if they weren't planning to sue for infringement of those patents? Facebook's calling the new terms "clearer" but the clause that they removed seemed pretty unambiguous in its intent.
