Probably because heads of telcos have said that Internet companies need to "pay their fair share." That means the company who wants to go on the ISP's lines needs to pay the ISP. Logically, companies that don't pay don't get through quite as well, or at all.
I think what you probably will see are bandwidth caps and plan changes.
That's fine. My main problem so far has been when companies advertised X bandwidth, contracted with customers for X bandwidth, and then penalized customers who actually used X bandwidth as "abusers" of the system. That and when X protocol used a lot of bandwidth, the ISP interfered with the traffic.
I'd rather see it done the non-neutral way and have Netflix sit down with the ISPs and work out a deal that would save both of their business models.
That's not the way the Internet works. Netflix is Level 3's customer to get the data out, you are your ISP's customer to get the data in. There is no direct business relationship between Netflix and your ISP. There are peering arrangements at the level of where the backbone networks meet, and that's a different and very complicated issue.
Okay, so call your ISP and get your own line. Or just get a business account. Then, you'll be paying the full freight for your connection.
Oh, and thanks for the 'very complicated' lesson in 'how the internet works'. It's always educational to converse with someone ignorant enough of history to advocate for the government imposing 'neutrality'. Thanks for taking the time and as Abraham Lincoln would say: Thanks for removing all doubt.
