Wikipedia shouldn't be so difficult to edit or highly politicized. There was a time when IP editors made the majority of contributions. Today correcting a typo might trigger a full-time editor to defend his turf. Even asking questions about an uncited assertion on a talk page can be labeled as disruptive.
I feel bad for the victims of the scam. It can be hard to edit or correct basic facts. Most business owners don't have time to specialize in Wikipedia lawfare. I have no sympathy for the WMF or the hard-core believers who wrote this expose'. Their policies created opportunities for these scammers to exploit.
The fact that they wrote this without an ounce of self-reflection or awareness of the problems is more troubling than the scam itself. Scams will come and go, but we've been stuck with Wikipedia as Google's and therefore the Internet's arbiter of "truthiness" for too long.
