It's one of those crud reports where someone pulls some superficial bits of information over some, what appears to be a rare phenomena, then someone else uses it to try to manufacture a panic, but even the language there seems over-blown ("at scale", scale, what scale).
Blowing up a panic over every random spammer or irrelevant site is silly.
And I think what was so stunning, was just how weak their arguments were, and particularly, what points they focused on.
It was very "there are bad people doing bad things somewhere on the Internet", then they tried to drum it up, and it just blew up in their faces when they tried to cherry-pick tiny numbers as "evidence" of it being some big bad thing.
