This is just pedantry completely ignoring the main point - of course, each tcp/ip connection sends bytes in both directions. But the connection to a residential customers (Netflix users) are very asymmetric - they are almost always initiated by user's initiative and have users request a lot of data flowing in their direction, while almost none flows in the opposite direction. It's not like Netflix just decides to send me a gigabyte of a movie. It's also not like we exchange gigabytes routinely in both directions. It's me asking to get the movie and paying for the privilege of getting it. The fact that technically a tiny stream of bytes also gets in other direction is irrelevant here.
I was being pedantic. If you'd note elsewhere I explain to others the asymmetric nature of consumer ISPs, so I'm not obtuse to the issue. I just believe that saying untrue things is unhelpful to the problem. I want to be called out when I'm wrong; I hope others do to. I don't believe I was mean while doing so.
Also, nothing I said despite it being asymmetric, just that his point about pushing and pulling isn't the best way of describing the issue.
