I feel this too. As Dave mentioned, Kevin is someone who left the FCC and came to the software world.
Someone from the FCC just said that they were part of the physical layer. Maybe it's this physical layer attitude, maybe it's the proximity with the government... There's something about the smile on Kevin's face and the sparkle in the eyes of the software guys clashing with the bit more serious looking and complicated arguments from the FCC guys which makes this feel more like a struggle between a community of software people vs. a community of physical layer folks.
