My best guess is the company just doesn't see much value in doing the work. It's a niche community and by definition 20+ year old information. It's important historically maybe but not to Google's business. No one's going to buy or see ads on 1990s rec.arts.sf.tv.babylon5 content. archive.org has several significant Usenet collections. Henry Spencer's UTZOO collection, stuff from Giganews, and some sort of dump for Google Groups / Deja itself. I don't think anyone's built a useful interface for them yet.
