I think the fight with content farms must be related to scrapper sites, example a news site which does not have original content or added value and only publish thousands of feeds.
Regarding sites like Demand Media which are often on the serps, i think things must be related to anti-monopoly policy. There are a lot of simple sites whithout advanced SEO on it and with useful content.
I hope they will keep the serps free, various sources of informations and no monopoly.
