Another use case that the author doesn't go into is the proliferation of penetration/injection/other security attack scripts that allows people to throw a battery of common attacks against dictionaries of sites. That's allowed malicious people to be malicious at scale.
I wonder what state of mind suggested throwing "asshole" around all over the place leads one to think it's a good stylistic device for a semi-technical article. The text feels like it's written by a 3-year-old just after learning a forbidden word.
