In my experience, Google may do something about it and may not. If the site has enough authority, Google may figure that search results pages from an authority site are still better than crap pages from a crap site. And if the percentage of good pages is significantly higher than the percentage of crap pages, the company may still get a pass.
Plus, we all know it takes Google a while to get around to everyone. In some cases, it's been years and years.
As far as the people in charge of these sites, in most cases they are probably aware of what they are doing, but I have consulted with companies (even big companies) who had no idea that their search results didn't belong in Google's search results.
It's not a strategy I would recommend, for anyone. Pretty much the first thing I do on any site is remove/block the search results page. Mostly just because I hate seeing them in Google myself.
