It's pretty much the opposite you have to be afraid of. Netflix is a big player and can force anyone to play ball with them. The problem is that anyone not named Netflix will have a much bigger hurdle to reach you.

Imagine you're a startup trying to compete with Netflix, and on top of having to create your business and media content, your customers have to pay their ISP a fee to access your website (or have better bandwidth, or have it not counted in your allocated data plan). No one would be able to compete with them. Now replace Netflix with any <Google, Facebook, Uber, any incumbent really>... and yeah you get the idea.
