BronsonLee edited that post to say that the image was unverified and they might have been bamboozled. In any event, there was no context where the image was from so we have no idea. 7-10GB/hr might be a decent estimate, as that's slightly higher than what 4K UHD YouTube streams at.
That said, though, you don't have to be nasty to people who are just having a conversation about this new technology. I think you've made your case that you hate this service and that it's, apparently, going to bring about the bankruptcy of soccer moms all over America (or... whatever that weird argument was), but you don't have to be snide to other posters. They're not Google.
