Many of those within Bob's group want to get out but are too afraid to leave. Little do they know that Bob has no real power. His lavish lifestyle makes him live in a perpetual state of debt and he is risk averse with his own Bitcoins. He needs his group's income to do moves.  If you leave, Bob ceases to be.

Already we can see how irrelevant he is. He threatened and threatened and threatened that he was going to crush the price down with his "might", and here we are one week later at 80 something satoshi and the community clearly behind David.  Bob is a bully with no power.
