You might have read it backwards: the message was very humble. Moxie was saying that he didn't deserve credit for what he had built, because if he had not built it someone else would have. So his work was best thought of as a product of history, rather than a product of Moxie.
On the contrary, while it conveys some difficult ideas, I find it quite humble to acknowledge that one's individual contribution to technology is not an act of genius but of inevitability.
I think we must have read two different speeches, because the one I read was Moxie stating that the invention of Signal was an inevitability, not him taking credit for it. But then it kind of sounds like you have an axe to grind on this topic?
The Levchin Award recipients are determined by the RWC Steering Committee, which this year was Dan Boneh, Aggelos Kiayias, Brian LaMacchia, Kenny Paterson, Tom Ristenpart, Tom Shrimpton, and Nigel Smart.
I think we can safely assume Moxie's popularity on HN had very little to do with persuading these people.
