Not quite sure where you're coming from here. RSS doesn't exactly take much effort to implement, you can make it update automatically and control what goes in it. For the large news sites featured on Google news it's true that they are often already using it, unlike most smaller sites. The advantage is that there is limited content that's been authorized, in exchange for links in to the site. For a lot of sites this is a good deal, and definitely better than getting a snippet linked to a search term, that could be part of a sentence out of context or even the most important nugget of information in the entire article.
