The point you're making is orthogonal to the point Aitel is. Aitel is saying that on a day-to-day operational basis, Russia and China are usually using a different set of vulnerabilities than the USG is. So, putting Russian discoveries of USG tradecraft aside, the point he's making is very simple: is the USG is obligated to disclose its bugs, and meanwhile Russia is clearly not and never will be, then Russia has an advantage: it's bugs are safe, but its adversary has to churn through new ones.
That's all I think he's saying.
