Google has decided to make its News product opt-in only in Germany in light of new copyright laws. The change will take place August 1. After that date, only news sites that have opted-in to the program will have their news stories appear in Google's News search engine.
The issue came about because Germany passed a new copyright law that takes place August 1. This law could see Google possibly having to pay publishers fees for indexing and returning snippets of their stories. Google wants to limit liability, so the only way to do that completely is to eliminate everyone and force opt-in.
Interested news publishers can head to Google's Webmaster Tools. Once there, they can opt-in to be indexed and returned as part of Google News. If publishers don't opt-in, they will be removed from the index on August 1.
Google argues that they were providing a free service that increased publishers' traffic. Some German publishers will be sure to opt-in, but a fair amount probably won't.
