I have a feeling that you are right - it's all about what binds the web togeter - how it is linked.
The question remains though, if there is a problem with the site or the way it is linked to why bother to maintain ranking? I think this points to unnatural linking practices but why be so elaborate about the punishment?
I have removed links from a site that I own that is basically an affiliate feed generated site as we know that google is targetting thin content sites - so I assume that they will have also targetted links from such sites. Long shot but it can't hurt (any more).
