The hell?
Half a gigabyte a month isn't my definition of sipping.
And as for this: The maximum bandwidth of a Sidewalk bridge to the Sidewalk server is 80Kbps
It is perhaps worth pointing out that a lot of people's broadband is highly asymmetrical. I, personally, get 3.5 megabit download, and about 720 kilobit upload. Townies can get around 20 megabits, but their upload is around one megabit, because by and large the majority of data is one way - Netflix to my/their eyeballs.
Now that 80Kbps is a larger share than trying to compare it to streaming an HD video.
