It seems a bit self centered to make their lost $8000 the focus of the article.

The title should have been: "how a single line of code cost our users probably more than $8000"

Totally. I live in a place where many (most?) ISP plans have limited monthly downloads. I'd be so pissed off if my monthly allowance was blown by this series of boneheaded decisions.

It was mentioned, at the bottom. One customer even had their ISP cancel their service.
