Netflix has started leveling blame publicly at internet service providers whose downloading is slow. Verizon is not amused. This raises an issue of the risk of taking on vendors openly. It is no guarantee that the vendor will change its ways and the bad relations one has fostered against the vendor might come back to hurt the company. Perhaps Netflix can get away with criticism because it is one of the largest pipeline users in the world with its multi-gigabyte downloading of movies to millions of customers. Netflix might be frustrated and tired of hearing customer complaints over an issue about which it can do nothing. One can say this much for its public warning. It caught ISPs’ attention. One will now have to see if anything is done about download speeds or whether Netflix’s PR move has backfired.
