Is it the content-preview (however small), the content-gathering or the linking that will cost money? Google could (re-)write the headlines and micro-summaries themselves (using machine-learning technologies) and just provide links, without copying anything from elsewhere for previewing purposes. Embedding no snippets and thumbnails at all from the media-/publisher websites would turn Google News into a text-only site, making it a lot less appealing to the audience.
