antiterra said it better than I could, but I had to downvote you. We're used to techie snobbishness all the time, but calling people whores for working in one sector instead of another is not only stupidly arrogant, it's offensive.
Would it be whoring if you took money from Zynga instead? Groupon? Facebook? Yelp? Or any number of other disreputable companies that have engaged in allegedly immoral/illegal behavior?
FWIW I don't even work in banking.
