The same could be said of Google's search engine itself: an autogenerated web site consisting of essentially nothing other than links to other places, many of them paid. But no one can deny that it's a useful site.

I think that is the issue here -- probably the vast majority of such sites are undesirable, but you can't discount them all.

But Google had to spend resources to crawl those other sites, collect the data those sites created, evaluate and order the results excerpting those sites' data based on a user's query, clearly adding value for the user performing a search... Oh, wait.
