Not surprising, when you consider that every intelligence agency spends at least 10x more money on offense than defense. I first became aware of this when I worked at a company where we had the NSA "defense" as a customer. We tried and tried to get contacts on the offense, because it was a much bigger market opportunity, but the company went under before we succeeded. So it's our Ferrari offense against their Fiat defense, and vice versa. (Not at all a comment on skills or motivation BTW. There might be an element of having one's pick of a larger talent pool, but mostly it's about resources.) It's practically inevitable that we'll both score lots of points off each other.
