Hmm,
a) In John Barlow's defence, he mostly just sounded conservative. Just like I no longer watch the prices and specs of the latest computer gear unless my old stuff breaks, and I don't care about MP3 players (Wow! Ipods with 20GB 2" hard drives
) or Iphone 5 or Windows 8, it seems understandable that despite Bitcoin's awesomeness most people just won't pay attention until reality catches up with them.
b) he's probably a bit scared of retaliation if he openly promotes Bitcoin too much.
c) Duh, he saw Bitcoin as competition to his product. Well done to Max and Stacy for helping him to regain his honesty!
