As for a commercial on TV when I buy a car, I always look at the company that I'm going to do business with and their reputation. Just because they haven't personally scammed or cheated me, doesn't mean it can't or won't happen and vigilance has kept it from happening to me and my friends. This has nothing to do with his private life and everything to do with his public and business life, period.
And the car company in this example would be bitcoin itself. You don't have BW client running on your computer. It is bitcoin that you have to thrust. You don't have to thrust the speaker of their commercials (BW).
So yes, examine the source code of the Bitcoin software. Check that there is no bad code in there, and so on. But BW? Why?
