YES! Yes they do! But Netflix doesn't send that traffic for fun and giggles, just to swamp your network and clog up the port. They do it because YOUR CUSTOMERS HAVE ASKED THEM TO and you, Verizon, you duplicitous shitbag, have SOLD THAT CAPABILITY to your customers. They have LITERALLY PAID you to successfully receive up to 75Mbps worth of traffic from ANYONE, INCLUDING NETFLIX.
I can't fucking stand this "they send a lot of traffic our way, but we don't send any back!" bullshit. Netflix doesn't PUSH traffic to your customers, your customers PULL traffic FROM Netflix.
