As for the message HBO focused on, if you consider that by that time Peter Todd already understood how Bitcoin transactions worked—after all, it was almost two years since the network's launch, and many people, including him, were familiar with the technology—there's nothing surprising about him reading Satoshi Nakamoto’s last post about transaction fees and simply adding his own thoughts on how he understood it. Moreover, it's clear that his message was not in Satoshi Nakamoto's style at all.
