Plan B
Perhaps providers of content could delivery shitty quality video to the networks of providers who try to squeeze them and their customers for profit. Nothing irritates a user more than a service they're using proving to be unreliable and inferior to their mates service. Or plan C, imagine...
"Dear Netflix subscriber,
Your carrier/isp charges netflix a premium to delivery our HD content to their customers advising us that if we didn't pay they would throttle our content, diminishing your experience. Unfortunately this necessitates a £1/month subscription premium to your service. Please feel free to use the affiliate links below to mobile/broadband partners who promise never to do this. All proceeds from the click-thrus will go toward <net neutrality orgs>
Sincerely
Netflix in your face Support"
