It seems to me more about charging extra or artificially throttling. If a streaming provider has massive connection at a shared upstream peering location as an ISP, but their competitor doesn't, the result could likely be that the bandwidth is better to that provider, while it's congested going to anywhere else on the internet (including competitors). Is this a violation of net neutrality, and if so, by who? Some other situations I can think of that are less clear: "Sorry streaming service, we can't host your CDN appliance because we already have an appliance from your competitor and our agreement with them disallows it" "Sorry streaming service, we can't host your CDN appliance because we have no more physical space" "Sure we'll host your CDN appliance, if you pay $$,$$$,$$$ to cover the cost of expanding our datacenter" "Sure we'll host your CDN appliance, it will cost you $,$$$,$$$ per year" "Sure we'll host your CDN appliance, it will cost you $$ per month per client IP"
