There's a transcript if you want to read, not listen. At the start, you'll be "hey! I gotta get me one!" and later you'll be like "burn it with fire!"

Interesting! According to this, a lot more going on beyond the residential proxy element, which was the only bit I had considered (or heard about). I wish there was an accompanying article with some more specifics.
