Interesting comparison to the "rootkit" case.

Interesting because EFF jumped to bring suit against Sony BMG on behalf of affected consumers, and other "consumer" groups like PK and Consumer's Union joined in condemning Sony BMG for hurting consumers.

Yet, these "consumer" groups are uncharacteristically passive and silent when it comes to advocating the interests of consumers deceived by KaZaA. No pro bono assistance? No press releases in support? No condemnation of KaZaA for consumer fraud and deceit?

Nor have these groups ever helped an individual copyright owner, like a graphic artist, photographer, or needlepoint designer, bring a copyright infringement suit against the corporate behemoths that exploit their works for commercial gain. Instead, they have taken the side of the corporate behemoths.

How to explain the failure of these "consumer" groups to consistently advocate the interests of the small guy?

The only consistency appears to be anti-copyright animus.
