I was hoping the article would cover what happened to UnderTheSite.com and how it came to redirect to BuiltWith. UnderTheSite was built so that members of the community could contribute fingerprints to detect previously undetected technologies. This seemed to work pretty well and had the advantage that it was one click to see the code of the fingerprint responsible for detecting that technology in order to debug false positives. I'm not surprised BuiltWith would diminish the story of how they profited from volunteers' work without compensating the volunteers, but it does strike me as lacking class that they completely remove this part of their story. Also it would be nice to have a better sense of "Why could this idea not succeed as an open source project?" (Eg., in an alternate history where UnderTheSite did not sell out to BuiltWith...)
