Bob was never 'bribed' or threatned with money.
I never suggested he was bribed or threatened. He was, however, compensated to run a website that was ultimately revealed to be against his principles. Clearly, he chose principles over money (his compensation).
Maybe I misunderstand, but I gather Bob didn't resign because of a better offer, to retire, or to begin a career as a full-time trader. I believe he resigned because he disagreed with the plan for this website; a plan that he probably considered questionable as do others.
