Since nobody has so far managed to hit the target:
This is Google acting as your network provider. You first choose Google, and then take your pick amongst their offerings. It's pretty much the same situation as it has always been for residential ISPs, where you have always had providers offering tiers at various speed/price points.
Net neutrality becomes relevant when you don't have a say in the choice of network. Practically, this will usually mean your audience's ISPs (called a "broadband provider" in that order). You get your servers set up at AWS, or GCE, or Linode or wherever you like the terms. But then, no matter what, you get an e-mail from some residential ISP in Florida, telling you that it'll cost you XX$ if you want to stream to your customers on their network at 1080p.
The problem is pretty obvious: the consumer choosing the ISP is not going to take your welfare into consideration, especially if your company doesn't even exist yet. The ISP won't be able to squeeze google, facebook, or amazon. But anything not used by 50%+ of the population simply has no power in these negotiations.
The result will be ISPs capturing almost every last cent you can earn amongst their customer base. If your service competes with any existing offering by either the ISP or a company with deeper pockets than yours, you will never have a chance to compete on quality.
Oh, and you won't just get an email from that ISP in Florida. You'll get an email from every single ISP in the world. Part of the startup decision making process will be like MadTV (if anybody remembers): should we invest these $2,000,000 into our product, or is it better spent on getting access to the markets in Iowa and eastern Michigan? Should we continue haemorrhaging money in southern Europe, or is time to cut our losses and go dark on that continent?
