Dont think there is any doubt Russian (and Chinese) hackers completely own most US infrastructure. Only need visit a few Russian hacking forums to see that. It "was easy" because the NSA put so much effort into making systems insecure. (Have the US government replaced those Juniper routers yet?)
The only "doubt" is whether or not they are working for their state or just condoned by their state.
Plus a big chunk of playing to public opinion because it's heresy to imply let alone state as fact that Russian or Chinese offensive comp sci is better than US defensive comp sci. Even though, in your hearts, you all know it to be true.
I wonder if deminishing "net neutrality" will be "yet another nail" in the copyright industries coffin.
The closest analogy I can think of to a historic non neutral network is AOL. And we (should) all know how that worked out.
