Google controlling piracy?

Readings "Google changes to fight piracy by highlighting legal sites" basically is about trying to get rid of sites that promote piracy and stealing of owned materials and also how companies could bribe to make their business come on top for search results. I honestly think the fight for piracy would not matter because from the movies one I seen and the tv shows websites that exist, the sites are mainly just host sites. Meaning that the site just exists to catalog material and when you find something you want to watch, it will either link you directly to the site to watch or get something, or redirect you in the direction of the material. The sites that Google might fight to get off are probably just the host sites. While sites could be compromised by the government and taken down, new sites could be made easily for the same hosting purposes.
