It's a great tactic, because Americans generally are not hostile toward very wealthy individuals when they perceive these individuals as wealth creators - in fact, they actually admire these people [1]. Yes, most support progressive taxation and would support higher taxes for the rich (even wealth creators whose activities we want to support), but they'd oppose a "soak the rich" kind of class warfare, on practical and moral grounds.
No surprise, then, that people who profited, first from risky and economically worthless activities [2], and next from a massive taxpayer supported bailout, would want to get real close to the founders of tech companies in silicon valley and hope that nobody notices the difference.
I'm not surprised that the movement against "wall street" is incoherent right now. There are so many angles, so many different opinions. You have the anarchists who protest globalization in general, but you also have Tim O'Reilly stating that he thinks wall street bankers got away with a crime [3] (and kept the money too).
As someone in high tech, the most important thing to me is to make sure that financial "engineers" don't get to associate themselves with the wealth creation of real engineers and other people who are wealthy because they created wealth.
[1] An interesting article about this in the nytimes titled "How we value the super rich" talks ab it about the mentality behind this distinction...
