I can say they definitely don't approve it, similar to theory11 although t11 at least left the ratings open for everyone. But those companies just treat it all as testimonials instead of actual reviews/comments/feedback, in that you never see magicians put bad quotes on their products either. The bad thing is that DnD and t11 make you believe that absolutely everyone has had their input while that has not been the case. Dishonesty all the way.
