The author points out some interesting problems with bitcoin's perception, but admits that they don't have a solution. I can imagine the slope of negative perception being slippery, but I'm also not sure there's anything honest people can do other than continuing to be honest and hoping they out power everyone else.
Though, I might be projecting bitcoin's technical properties onto its social layer:
The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.
