This is why we can't have nice things
This is why we can't have nice things. But knowing that people are going to do this sort of thing, then obviously we should design in defences against it. Even though the engineering involved is going to make the system 5 to 10x more expensive to deploy.
It still rather sticks in the throat that the ones who'll be doing this defensive engineering are probably the same one who would otherwise attack the system. It's like a protection racket run by nerds.
