This is another example of what I call "barbarians at the gate". I didn't come up with that phrase. I don't remember where I first came into contact with that phrase.
The idea, as best as I can recall, is something like this: The empire won't fall simply because of the increasing decadence of the empire. It falls because it eventually gets weak enough that the barbarians, ever-present at the gate, can bring it down with a simple raid.
These people are "barbarians at the gate". They don't care that they are trying to destroy the Internet. They are after chaos or, maybe, simply trying to "earn" a dollar. They are no different to ISIS. That group of fanatics trying to force the world to submit to their stupidly strict interpretation of Islam. Or to those hate-mongers in many forums who should probably have "Poor Impulse Control" tattooed on their forehead... i.e. Barbarians.
I think I first came across the phrase in a book by Larry Niven.
