It's unlikely popular and profitable services will be hindered by the lack of net neutrality. But any new services that threaten existing ones will be hard-pressed to compete. Imagine I start a new streaming service. In order for my service to reach people, ISP's will charge me a higher price than Netflix, probably a _significantly_ higher rate. This will make it extremely difficult for my new service to reach enough…
But Netflix is already getting a better deal than start ups at many ISPs. Netflix gets free rackspace for their CDN servers. No start up gets that.
There is already a "fast lane" in many ISPs and Netflix gets it for free.
