Well, I know Adam Back personally, but this is an anon account so I won’t say more.
He has also made numerous flubs when describing bitcoin that betray a lack of understanding of the incentives underlying bitcoin which satoshi would have known.
The type of ecash he wrote about prior to bitcoin was fundamentally very different. Bitcoin is not an evolution of hashcash like systems. It is fundamentally different by embracing an eventually consistent model which was antithetical to the approaches taken by Back, Szabo, etc.
