Asymmetric data flow is intrinsic to the service Verizon sells to the majority of it's last mile customers. It's pretty much intrinsic to DSL that the download bandwidth you get is vastly higher than the upload bandwidth.
When you buy that download bandwidth from Verizon, there's nothing in the fine print that says what you may or may not fill it with. If you fill it with Netflix video, that's your business because you paid for it. It's not Verizon's because they have sold it to you, and it's not Netflix's because you requested the data. It's your data that you paid Netflix for traveling to you on your bandwidth you paid Verizon for.
