You seem to be arguing, but that's the guy's point: Netflix couldn't be doing this, because the decision in that frame to crop the left off isn't something an automated algorithm is going to do, nor is it reasonable to believe that Netflix has people going through making all of these decisions; the result is that we must believe that Netflix is being given these modified movies by the studios, as opposed it being Netflix's decision to make the modification (as proposed in etler's parent comment by mullingitover).
