I significantly doubt the premise of this article is true. If you read into Snowden's background, the job at Booz Allen was quite a lucky gig for him. Having no formal education, to include a high school degree, he managed to climb his way to a 6 figure salary at a big firm, anyway, nonetheless, a defense contractor.

Sorry, but I don't buy it. It seems much more likely that he really needed the job and was fortunate to have it, but felt guilty about what he saw there, or just got pissed off and decided to leak.
