I don't see the relevance. Linux is no good target, because there are not many linux boxes compared to windows/mac and because 100 linux boxes might require 10 different ways to attack them, while 100 windows boxes might require 1 or 2. There is nothing obscure here, just diversity.
Diversity is always a good tacit in defeating pest.
Learn from nature / biology. Monocultures are unstable and have to be superficially stabilized with great effort.
